This replaces most of the calls to netdev_alloc_skb_ip_align in the Realtek
drivers. The one instance I didn't replace in 8139cp.c is because it was
called as a part of init and as such is not always accessed from the
softirq context.

This change replaces calls to netdev_alloc_skb_ip_align with
napi_alloc_skb. The advantage of napi_alloc_skb is currently the fact that
the page allocation doesn't make use of any irq disable calls.
There are few spots where I couldn't replace the calls as the buffer
allocation routine is called as a part of init which is outside of the
softirq context.

Commit 97a6d1bb2b (xen-netfront: Fix
handling packets on compound pages with skb_linearize) attempted to
fix a problem where an skb that would have required too many slots
would be dropped causing TCP connections to stall.
However, it filled in the first slot using the original buffer and not
the new one and would use the wrong offset and grant access to the
wrong page.
Netback would notice the malformed request and stop all traffic on the
VIF, reporting:

pull request: wireless-next 2014-12-08
Please pull this last batch of pending wireless updates for the 3.19 tree...
For the wireless bits, Johannes says:
"This time I have Felix's no-status rate control work, which will allow
drivers to work better with rate control even if they don't have perfect
status reporting. In addition to this, a small hwsim fix from Patrik,
one of the regulatory patches from Arik, and a number of cleanups and
fixes I did myself.
Of note is a patch where I disable CFG80211_WEXT so that compatibility
is no longer selectable - this is intended as a wake-up call for anyone
who's still using it, and is still easily worked around (it's a one-line
patch) before we fully remove the code as well in the future."
For the Bluetooth bits, Johan says:
"Here's one more bluetooth-next pull request for 3.19:
- Minor cleanups for ieee802154 & mac802154
- Fix for the kernel warning with !TASK_RUNNING reported by Kirill A.
Shutemov
- Support for another ath3k device
- Fix for tracking link key based security level
- Device tree bindings for btmrvl + a state update fix
- Fix for wrong ACL flags on LE links"
And...
"In addition to the previous one this contains two more cleanups to
mac802154 as well as support for some new HCI features from the
Bluetooth 4.2 specification.
From the original request:
'Here's what should be the last bluetooth-next pull request for 3.19.
It's rather large but the majority of it is the Low Energy Secure
Connections feature that's part of the Bluetooth 4.2 specification. The
specification went public only this week so we couldn't publish the
corresponding code before that. The code itself can nevertheless be
considered fairly mature as it's been in development for over 6 months
and gone through several interoperability test events.
Besides LE SC the pull request contains an important fix for command
complete events for mgmt sockets which also fixes some leaks of hci_conn
objects when powering off or unplugging Bluetooth adapters.
A smaller feature that's part of the pull request is service discovery
support. This is like normal device discovery except that devices not
matching specific UUIDs or strong enough RSSI are filtered out.
Other changes that the pull request contains are firmware dump support
to the btmrvl driver, firmware download support for Broadcom BCM20702A0
variants, as well as some coding style cleanups in 6lowpan &
ieee802154/mac802154 code.'"
For the NFC bits, Samuel says:
"With this one we get:
- NFC digital improvements for DEP support: Chaining, NACK and ATN
support added.
- NCI improvements: Support for p2p target, SE IO operand addition,
SE operands extensions to support proprietary implementations, and
a few fixes.
- NFC HCI improvements: OPEN_PIPE and NOTIFY_ALL_CLEARED support,
and SE IO operand addition.
- A bunch of minor improvements and fixes for STMicro st21nfcb and
st21nfca"
For the iwlwifi bits, Emmanuel says:
"Major works are CSA and TDLS. On top of that I have a new
firmware API for scan and a few rate control improvements.
Johannes find a few tricks to improve our CPU utilization
and adds support for a new spin of 7265 called 7265D.
Along with this a few random things that don't stand out."
And...
"I deprecate here -8.ucode since -9 has been published long ago.
Along with that I have a new activity, we have now better
a infrastructure for firmware debugging. This will allow to
have configurable probes insides the firmware.
Luca continues his work on NetDetect, this feature is now
complete. All the rest is minor fixes here and there."
For the Atheros bits, Kalle says:
"Only ath10k changes this time and no major changes. Most visible are:
o new debugfs interface for runtime firmware debugging (Yanbo)
o fix shared WEP (Sujith)
o don't rebuild whenever kernel version changes (Johannes)
o lots of refactoring to make it easier to add new hw support (Michal)
There's also smaller fixes and improvements with no point of listing
here."
In addition, there are a few last minute updates to ath5k,
ath9k, brcmfmac, brcmsmac, mwifiex, rt2x00, rtlwifi, and wil6210.
Also included is a pull of the wireless tree to pick-up the fixes
originally included in "pull request: wireless 2014-12-03"...
Please let me know if there are problems!

On Atmel AT91, the conversion to device tree is now considered complete,
and all machines that were not already converted in 3.18 are assumed to
be unused and dropped by the maintainer.
All remaining board files that were written in C are dropped, and the
ancient at91x40 sub-platform (based on an MMU-less ARM7) is removed
altogether. Cleaning up the last pieces was great fun, so I took the
time to do some of the coding myself and removed several hundred code
lines that ended up unused after the board files were done.
There are still a couple of AT91 specific device drivers that are not
converted to DT (CF, USB-OTG) and currently not working, and the platform
itself is not "multiplatform"-enabled, but both issues are going to be
taken care of in the 3.20 cycle.
This is split out from the other cleanups purely based on the size
of the branch.

Intel Wired LAN Driver Updates 2014-12-09
This series contains updates to i40e and i40evf.
Jeff (me) provides a single patch to convert a macro to a static inline
function based on feedback from Joe Perches on a previous patch.
Shannon provides the remaining twelve patches against i40e. Almost all
of Shannon's patches cleanup/fix NVM issues varying in range from
adding more detail to debug messages, to removing dead code, to fixing
NVM state transitions after an error. Change the handy decoder interface
for admin queue return code to help catch and properly report the condition
as a useful errno rather than returning a misleading '0'. Added a range
check to avoid any possible array index-out-of-bound issues.
v2:
- fixed up patch 05 in the series to use the ARRAY_SIZE() macro as suggested
by Sergei Shtylyov
- fix up patch 13 to remove unnecessary parens in the return statement
as suggested by Sergei Shtylyov

Since commit fbe168ba91 ("net: generic dev_disable_lro() stacked

first for a macvlan device and then for its lower device. As an attempt
to set NETIF_F_LRO to zero is ignored, dev_disable_lro() issues a
warning and taints kernel.
Allowing NETIF_F_LRO to be set independently of the lower device
consists of three parts:
- add the flag to hw_features to allow toggling it
- allow setting it to 0 even if lower device has the flag set
- add the flag to MACVLAN_FEATURES to restore copying from lower
device on macvlan creation

The adminq init is run after the EMPR that is triggered by the
NVM update. The final write command will cause the reset and
will want to wait for the ARQ event that signals the end of the
update, but the reset precludes the event being sent. The state
is probably already at INIT, but we set it so here anyway, and
clear the release_on_done flag as well.

Rework the debug messages in the NVM update state machine so that we can
turn them on and off dynamically rather than forcing a recompile/reload.
These can now be turned on with something like:
ethtool -s eth1 msglvl 0xf000008f
and off with:
ethtool -s eth1 msglvl 0xf000000f
The high 0xf0000000 gets the driver's attention that we want to change the
internal debug flags, and the 0x80 bit is the NVM debug.

The NVM update operations take time finish asynchronously, and follow-on
update requests need to wait for the current one to finish. Early
firmware didn't handle this well, so the code had to track the busy state.
The released firmware handles the busy state correctly, returning
I40E_AQ_RC_EBUSY if an update is still in progress, so the code no longer
needs to track this.

Our FW can support several fastpath HSI [for backward compatibility] but up
until now VFs were always configured to use latest fastpath HSI [although VF
driver might be older and use an older fastpath HSI].
For linux drivers, the differences are insignificant since driver never
utilized features that were overridden by the HSI change. But for VMs running
other operating systems this might be a problem.
In addition, eventually FW might change fastpath HSI in such a manner that
backward compatibility WILL break unless configured with proper version.
This patch fixes the issue for other operating system VMs, as well as lays
the ground work for forward compatibility in regard to the fastpath HSI.

The comment says that the built-in strncmp didn't work. That is not
surprising, as apparently "str" semantics are not really what is
wanted (hint: de4x5_strncmp only stops when two different bytes are
encountered or the end is reached; not if either byte happens to be
0). de4x5_strncmp is actually a memcmp (except for the signature and
that bytes are not necessarily treated as unsigned char); since only
the boolean value of the result is used we can just replace
de4x5_strncmp with memcmp.

It modifies drivers implementation of set/get_rxfh accordingly.
This change also delegates the responsibility of checking whether a

driver implementation of set_rxfh.
User-kernel API is done through the new hfunc bitmask field in the
ethtool_rxfh struct. A bit set in the hfunc field is corresponding to an
index in the new string-set ETH_SS_RSS_HASH_FUNCS.
Got approval from most of the relevant driver maintainers that their
driver is using Toeplitz, and for the few that didn't answered, also
assumed it is Toeplitz.

Intel Wired LAN Driver Updates 2014-12-06
This series contains updates to i40e and i40evf.
Shannon provides several patches to cleanup and fix i40e. First removes
an unneeded break statement in i40e_vsi_link_event(). Then removes
some debug messages that really do not give any useful information and
ends up getting printed every service_task loop, which fills the logfile
with noise when AQ tracing is enabled. Updates the aq_cmd arguments to
use %i which is much more forgiving and user friendly than the more
restrictive %x, or %d. Fixes the netdev_stat macro, where the old
xxx_NETDEV_STAT() macro was defined long before the newer
rtnl_link_stats64 came into being, and just never got updated.
Getting the pf_id from the function number had an issue when
when the PF was setup in passthru mode, the PCI bus/device/function
was virtualized and the number in the VM is different from the number in
the bare metal. This caused HW configuration issues when the wrong pf_id
was used to set up the HMC and other structures. The PF_FUNC_RID register
has the real bus/device/function information as configured by the BIOS,
so use that for a better number.
Carolyn adds additional text description for the base pf0 and flow
director generated interrupts, since these interrupts are difficult
to distinguish per port on a multi-function device.
Jacob resolves an issue related to images with multiple PFs per
physical port. We cannot fully support 1588 PTP features, since only
one port should control (i.e. write) the registers at a time. Doing
so can cause interference of functionality.
Anjali provides several updates to i40e, first adds the Virtual Channel
OP event opcode for CONFIG_RSS, so that the Virtual Channel state
machine can properly decipher status change events. Then updates the
driver to add (and use) i40e_is_vf macro for future expansion when new
VF MAC types get added. Adds new update VSI flow to accommodate a
firmware dix with VSI loopback mode. All VSIs on a VEB should either
have loopback enabled or disabled, a mixed mode is not supported for a
VEB. Since our driver supports multiple VSIs per PF that need to talk to
each other make sure to enable Loopback for the PF and FDIR VSI as well.
Mitch provides a couple of i40e and i40evf patches. First updates
i40evf init code more adept at handling when multiple VFs attempt
to initialize simultaneously.
Joe Perches provides a i40e patch which resolves a compile warning
about about frame size being larger than 2048 bytes by reducing the
stack use by using kmemdup and not using a very large struct on the
stack.
v2:
- Dropped patch 13 & 14 while Mitch reworks the patches based on
feedback from Ben Hutchings, probably the tryptophan in the turkey
is to blame for the delay...
- Added Joe Perches patch which resolves a compile warning about frame
size

The mvneta driver sets the amount of Tx coalesce packets to 16 by
default. Normally that does not cause any trouble since the driver
uses a much larger Tx ring size (532 packets). But some sockets
might run with very small buffers, much smaller than the equivalent
of 16 packets. This is what ping is doing for example, by setting
SNDBUF to 324 bytes rounded up to 2kB by the kernel.
The problem is that there is no documented method to force a specific
packet to emit an interrupt (eg: the last of the ring) nor is it
possible to make the NIC emit an interrupt after a given delay.
In this case, it causes trouble, because when ping sends packets over
its raw socket, the few first packets leave the system, and the first
15 packets will be emitted without an IRQ being generated, so without
the skbs being freed. And since the socket's buffer is small, there's
no way to reach that amount of packets, and the ping ends up with
"send: no buffer available" after sending 6 packets. Running with 3
instances of ping in parallel is enough to hide the problem, because
with 6 packets per instance, that's 18 packets total, which is enough
to grant a Tx interrupt before all are sent.
The original driver in the LSP kernel worked around this design flaw
by using a software timer to clean up the Tx descriptors. This timer
was slow and caused terrible network performance on some Tx-bound
workloads (such as routing) but was enough to make tools like ping
work correctly.
Instead here, we simply set the packet counts before interrupt to 1.
This ensures that each packet sent will produce an interrupt. NAPI
takes care of coalescing interrupts since the interrupt is disabled
once generated.
No measurable performance impact nor CPU usage were observed on small
nor large packets, including when saturating the link on Tx, and this
fixes tools like ping which rely on too small a send buffer. If one
wants to increase this value for certain workloads where it is safe
to do so, "ethtool -C $dev tx-frames" will override this default
setting.
This fix needs to be applied to stable kernels starting with 3.10.

This is an attempt to correct that problem.

When multiple VFs attempt to initialize simultaneously, the firmware may
delay or drop messages. Make the init code more adept at handling these
situations by a) reinitializing the admin queue if the firmware fails to
process a request, and b) resending a request if the PF doesn't answer.
Once the request has been sent again, the PF might end up getting both
requests and send the configuration information to the driver twice.
This will cause the VF to complain about receiving an unexpected message
from the PF. Since this is not fatal, reduce the warning level of the
log messages that are generated in response to this event.

Resolve an issue related to images with multiple PFs per physical
port. We cannot fully support 1588 PTP features, since only one port
should control (ie: write) the registers at a time. Doing so can cause
interference of functionality.
It may be possible to partially implement the API for only those
features without side effects. However, this at minimum means non
controlling PFs lose Tx timestamps, frequency atunement, and possibly
SYSTIME adjustment. There may be further impact I did not discover.
Since the API in the kernel expects these features to work, it is
simpler and less dangerous to just disable PTP features on all PFs not
identified as the controlling PF in PRTTSYN_CTL0.PF_ID.
This change also removes the warning printed when hwtstaml IOCTL is
called on the wrong PF. This is actually meaningless now, since only one
PF per port will support it. In addition, the ethtool get_ts_info IOCTL
was updated so that only the controlling port will even indicate support
(so as not to confuse users).
The overall downside is complete loss of functionality on non
controlling PF, vs the possible gain of partial support. The biggest
factor for choosing this approach is simplicity and ensuring that the
main PF will work. There could easily be other portions of the 1588
logic with side effects I am not aware, and the reduced functionality
that might be made available is significantly less useful. In addition,
the API does not allow for proper indication of why particular features
are not supported. These reasons are enough to decide for the simpler
approach to resolving this issue.

systems. Since we are no longer using the header split feature the upper
32 bits of the address no longer need to be cleared. As a result we can

Wake On Lan was not working on laptop DELL Vostro 1500.
If WOL was turned on, BCM4401 was powered up in suspend mode. LEDs blinked.
But the laptop could not be woken up with the Magic Packet. The reason for
that was that PCIE was not enabled as a system wakeup source and
therefore the host PCI bridge was not powered up in suspend mode.
PCIE was not enabled in suspend by PM because no child devices were
registered as wakeup source during suspend process.
On laptop BCM4401 is connected through the SSB bus, that is connected to the
PCI-Express bus. SSB and B44 did not use standard PM wakeup functions
and did not forward wakeup settings to their parents.
To fix that B44 driver enables PM wakeup and registers new wakeup source
using device_set_wakeup_enable(). Wakeup is automatically reported to the parent SSB
bus via power.wakeup_path. SSB bus enables wakeup for the parent PCI bridge, if there is any
child devices with enabled wakeup functionality. All other steps are
done by PM core code.

Add L2 bridge offloading support to rocker driver. Here, the Linux bridge
driver is used to collect swdev ports into a tagged (or untagged) VLAN
bridge. The switchdev will offload from the bridge driver the following L2
bridging functions:
- Learning of neighbor MAC addresses on VLAN X Learned mac/vlan is
installed in bridge FDB. (And removed when device unlearns mac/vlan).
Learning must be turned off on each bridge port to disable the feature in
the bridge driver.
- Flooding of multicast/broadcast and unknown unicast pkts to (STP)
active ports in bridge. The bridge driver is unaware of the flooding happening
at the device level. Flooding must be turned off on each bridge port to
disable the feature on the bridge driver.
- STP port state is pushed down to driver/device. The bridge still processes
STP BDPUs and maintains port STP state (for all VLANs in bridge), but
the driver/device must be notified of port STP state change to program
the device.
Multiple (VLAN) bridges are supported. The device (implemented per
the OF-DPA spec) must use a portion of the VLAN namespace for
internal VLANs. Right now, the upper 255 VLANs (0xf00 to 0xffe) are
used as internal VLAN IDs for untagged traffic and are not available
as port VLANs.
The driver uses the following interfaces:
1. To track VLAN add/del on ports in bridge:
.ndo_vlan_rx_add_vid
.ndo_vlan_rx_kill_vid
2. To track port add/del membership in bridge:
NETDEV_CHANGEUPPER netdevice notifier
3. To catch static FDB entries installed on bridge/vlan by user using netlink:
.ndo_fdb_add
.ndo_fdb_del
4. To be notified on port STP state change:
.ndo_switch_port_stp_update
5. To notify bridge driver on learned/forgotten mac/vlans on bridge port:
br_fdb_external_learn_add
br_fdb_external_learn_del

The rocker driver maintains 4 hash tables: flows, groups, FDB, and VLANs.
Flow and group tables track the entries installed to OF-DPA tables,
per the OF-DPA spec. See OF-DPA spec for full description of fields
in each flow and group table. New table entries are pushed to the
device with ADD cmd. Updated entries are pushed to the device with
MOD cmd. For flow table entries, a crc32 key is made from fields of
the particular field. For group table entries, the group_id is used
as the key.
The FDB table tracks fdb entries learned by the device or manually
pushed to the bridge by the user. A crc32 key is made from the
port/mac/vlan tuple for the fdb entry.
The VLAN table tracks the ifindex-to-internal-vlan mapping for
untagged pkts. On ingress, an untagged pkt is inserted with an
internal VLAN ID based on the input port's current internal VLAN ID.
The input port's internal VLAN will either be referenced by the port's
ifindex, if not bridged, or the containing bridge's ifindex, if
bridged. Since the ifindex space isn't within a fixed range, uses a
hash table (with ifindex as key) to track internal VLAN ID for a given
ifindex. The internal VLAN ID range is fixed and currently uses the
upper 255 VLAN IDs, starting at 0xf00.

These BUGs can be erroneously triggered by frags which refer to
tail pages within a compound page. The data in these pages may
overrun the hardware page while still being contained within the
compound page, but since compound_order() evaluates to 0 for tail
pages the assertion fails. The code already iterates through
subsequent pages correctly in this scenario, so the BUGs are
unnecessary and can be removed.
