4a0c081eff net: bcmgenet: call bcmgenet_dma_teardown in bcmgenet_fini_dma
We should not be manipulaging the DMA_CTRL registers directly by writing
0 to them to disable DMA. This is an operation that needs to be timed to
make sure the DMA engines have been properly stopped since their state
machine stops on a packet boundary, not immediately.

Make sure that tha bcmgenet_fini_dma() calls bcmgenet_dma_teardown() to
ensure a proper DMA engine state. As a result, we need to reorder the
function bodies to resolve the use dependency.

478a010c92 net: bcmgenet: fix TX reclaim accounting for fragments
The GENET driver supports SKB fragments, and succeeds in transmitting
them properly, but when reclaiming these transmitted fragments, we will
only update the count of free buffer descriptors by 1, even for SKBs
with fragments. This leads to the networking stack thinking it has more
room than the hardware has when pushing new SKBs, and backing off
consequently because we return NETDEV_TX_BUSY.

Fix this by accounting for the SKB nr_frags plus one (itself) and update
ring->free_bds accordingly with that value for each iteration loop in
__bcmgenet_tx_reclaim().

07d92d5cc9 macvlan: allow to enqueue broadcast pkt on virtual device
Since commit 412ca1550c ("macvlan: Move broadcasts into a work queue"), the
driver uses tx_queue_len of the master device as the limit of packets enqueuing.
Problem is that virtual drivers have this value set to 0, thus all broadcast
packets were rejected.
Because tx_queue_len was arbitrarily chosen, I replace it with a static limit
of 1000 (also arbitrarily chosen).

f4fd40b26b mlx4: Fix mlx4 reg/unreg mac to work properly with 0-mac addresses
There is a chance that the VF mlx4 RoCE driver (mlx4_ib) may see a 0-mac
as the current default MAC address when a RoCE interface first comes up.

In this case, the RoCE driver registers the 0-mac to get its MAC index --
used in the INIT2RTR transition when it creates its proxy Q1 qp's.

If we do not allow QP1 to be created, the RoCE driver will not come up.
If we do not register the 0-mac, but simply use a random mac-index,
QP1 will attempt to send packets with an someone's else source MAC which
will get the system into more troubled.

Since a 0-mac was previously used to indicate a free slot, this leads to
errors, both when the 0-mac is registered and when it is unregistered.

The required fix is to check in addition that the slot containing the
0-mac has a reference count of zero.

Additionally, when comparing MAC addresses, need to mask out the 2 MSBs
of the u64 mac on both sides of the comparison.

Note that when the EN driver (mlx4_en) comes up, it set itself a proper
mac --> the RoCE driver gets to be notified on that and further handing
is done with the update qp command, as was added by commit 9433c18891
("IB/mlx4: Invoke UPDATE_QP for proxy QP1 on MAC changes").

0d0162e7a3 net: allow macvlans to move to net namespace
I cannot move a macvlan interface created on top of a bonding interface
to a different namespace:

% ip netns add dummy0
% ip link add link bond0 mac0 type macvlan
% ip link set mac0 netns dummy0
RTNETLINK answers: Invalid argument
%

The problem seems to be that commit f939981492 ("bonding: Don't allow
bond devices to change network namespaces.") sets NETIF_F_NETNS_LOCAL
on bonding interfaces, and commit 797f87f83b ("macvlan: fix netdev
feature propagation from lower device") causes macvlan interfaces
to inherit its features from the lower device.

NETIF_F_NETNS_LOCAL should not be inherited from the lower device
by a macvlan.

After sending a RTR frame the TX mailbox becomes a RX_EMPTY mailbox. To avoid
side effects when the RX-FIFO is full, this patch puts the TX mailbox into
TX_INACTIVE mode in the transmission complete interrupt handler. This, of
course, leaves a race window between the actual completion of the transmission
and the handling of tx-complete interrupt. However this is the best we can do
without busy polling the tx complete interrupt.

    ERR005829: FlexCAN: FlexCAN does not transmit a message that is enabled to

Workaround: The workaround consists of two extra steps after setting up a
message for transmission:

Step 8: Reserve the first valid mailbox as an inactive mailbox (CODE=0b1000).
If RX FIFO is disabled, this mailbox must be message buffer 0. Otherwise, the
first valid mailbox can be found using the "RX FIFO filters" table in the
FlexCAN chapter of the chip reference manual.

Step 9: Write twice INACTIVE code (0b1000) into the first valid mailbox.

Reported by Nikolay Aleksandrov.  In efx_init_port() we call
 efx_mac_reconfigure() to work around a Falcon/A1 limitation, and this calls
 efx_{arch}_filter_sync_rx_mode(), which takes the addr_list_lock; but this
 lock is uninitialised, because we haven't called register_netdevice() yet.
So, in efx_farch_filter_sync_rx_mode(), check efx_dev_registered() before
 doing anything else.
The EF10 equivalent, efx_ef10_filter_sync_rx_mode(), already has the
 corresponding check.

87c4790330 brcmfmac: handle IF event for P2P_DEVICE interface
The firmware notifies about interface changes through the IF event
which has a NO_IF flag that means host can ignore the event. This
behaviour was introduced in the driver by:

  commit 2ee8382fc6
  Author: Arend van Spriel <arend@broadcom.com>
  Date:   Sat Aug 10 12:27:24 2013 +0200

      brcmfmac: ignore IF event if firmware indicates it

It turns out that the IF event for the P2P_DEVICE also has this
flag set, but the event should not be ignored in this scenario.
The mentioned commit caused a regression in 3.12 kernel in creation
of the P2P_DEVICE interface.

8f2b45971b brcmfmac: obtain ifp through wdev structure
For P2P_DEVICE interface the function brcmf_cfg80211_update_proto_addr_mode()
resulted in a crash, because it assumed wdev->netdev would be valid. The
ifp should be obtained through the driver vif structure which contains the
wireless_dev.

f1d56039b5 brcmfmac: conditionally compile firmware protocol source code
The host-interface can select which protocol implementation it
needs. Selecting PCIe will include the msgbuf protocol and selecting
USB and/or SDIO will include the bcdc protocol. The PCIe kconfig
option assures the dependencies for msgbuf are met, ie. HAS_DMA.

9a72c2da69 bonding: fix div by zero while enslaving and transmitting
The problem is that the slave is first linked and slave_cnt is
incremented afterwards leading to a div by zero in the modes that use it
as a modulus. What happens is that in bond_start_xmit()
bond_has_slaves() is used to evaluate further transmission and it becomes
true after the slave is linked in, but when slave_cnt is used in the xmit
path it is still 0, so fetch it once and transmit based on that. Since
it is used only in round-robin and XOR modes, the fix is only for them.
Thanks to Eric Dumazet for pointing out the fault in my first try to fix
this.

====================
pull request: wireless 2014-09-11

Please pull this batch of fixes intended for the 3.17 stream:

For the mac80211 bits, Johannes says:

"Two more fixes for mac80211 - one of them addresses a long-standing
issue that we only found when using vendor events more frequently;
the other addresses some bad information being reported in userspace
that people were starting to actually look at."

For the iwlwifi bits, Emmanuel says:

"I re-enable scheduled scan on firmware that contain the fix for
the bug that Linus reported.  A few trivial fixes: endianity issues,
the same DTIM period fix that I did in mac80211.  Eyal fixes a few
issues we identified with EAPOL, we now send them just as if they were
management frames, this solves interrop issues.  Johannes has another
set of trivial fixes, while Luca fixes the way we configure the filters
in the firmware. Last but not least, a new device is added by Oren."

Emmanuel was traveling, resulting in his pull to be a bit larger than
I would have liked to see at this point.  FWIW, I have asked Emmanuel
to be much more strict for any more pull requests in this cycle.

In addition to the above, Sujith Manoharan reverts an earlier ath9k
patch.  The earlier change was found to allow for the device to sleep
too long and miss beacons.

7ce7679d6b net: arc_emac: enable tx interrupts
In the current implementation the cleaning of tx ring is done by the
NAPI poll handler, which is scheduled after rx interrupts. Thus, in
absence of received packets the reclaim of used tx buffers is never
executed, blocking further transmission.

This can be easily reproduced starting the transmission of a UDP flow
with iperf, which blocks almost immediately because skbs are not
returned to the stack and the socket send buffer becomes full.

The patch enables tx interrupts so that the tx reclaim is scheduled
after completed transmissions.

ae0fd63541 Revert "ath9k: Calculate sleep duration"
This reverts commit 09ebb81092.

ath9k_hw_set_sta_beacon_timers() configures AR_TIM_PERIOD with
the beacon interval. Before this commit, the sleepduration was
never greater than the beacon interval. But now, the behavior
has changed. For example, with an AP that uses a beacon interval of 100:

ath: phy9: next beacon 61128704
ath: phy9: beacon period 204800
ath: phy9: DTIM period 204800

If the sleepduration is calculated based on the listen time, then
the bmiss threshold should also be changed since the HW would
be in sleep state for a longer time, but that is not done currently.

To avoid configuring a higher beacon interval based on the sleepduration,
revert to the original behavior. Power consumption is not a
problem since PS is disabled in ath9k anyway.

Fix that by doing this policy change using INIT2RTR only if the firmware

Single port VFs are seen PCI wise on both ports of the PF (we don't have

virtualization tools to try and configure a single ported VF through
