If the device mac address is updated using ndo_set_mac_address(),
while the same mac address is already programmed, the driver does not
detect this condition if its netdev->dev_addr has been changed. The
driver tries to add the same mac address resulting in mac address
collision error. This has been observed in bonding mode-5 configuration.
To fix this, store the mac address configured in HW in the adapter
structure. Use this to compare against the new address being updated
to avoid collision.

If a mac address is added to the uc_list and later the same mac address
is added via ndo_set_mac_address() or vice versa, the driver does not
detect this condition and tries to add it again. This results in a mac
address collision error when the FW rejects it.
Fix this by checking if the given mac address is present in uc_list while
setting the device mac address and vice versa. Similarly skip deletion if
the address is still in use in the other form.

This patch supports recovery from UEs caused due to Transient Parity
Errors (TPE), in BE2, BE3 and Skyhawk adapters. This change avoids
system reboot when such errors occur. The driver recovers from these
errors such that the adapter resumes full operational status as prior
to the UE.
Following is the list of changes in the driver to support this:
o The driver registers its UE recoverable capability with ARM FW at init
time. This also allows the driver to know if the feature is supported in
the FW.
o As the UE recovery requires precise time bound processing, the driver
creates its own error recovery work queue with a single worker thread (per
module, shared across functions).
o Each function runs an error detection task at an interval of 1 second as
required by the FW. The error detection logic already exists for BEx/SH,
but it now runs in the context of a separate worker thread.
o When an error is detected by the task, if it is recoverable, the PF0
driver instance initiates a soft reset, while other PF driver instances
wait for the reset to complete and the chip to become ready. Once
the chip is ready, all driver instances including PF0, resume to
reinitialize the respective functions.
o The PF0 driver checks for some recovery criteria, to determine if the
recovery can be initiated. If the criteria is not met, the PF0 driver does
not initiate a soft reset, it retains the existing behavior to stop
further processing and requires a reboot to get the chip to operational
state again.
o To allow each function to share the workq, while also making progress in
its recovery process, a per-function recovery state machine is used.
The per-function tasks avoid blocking operations like msleep() while in
this state machine (until reinit state) and instead reschedule for the
required delay.
o With these changes, the existing error recovery code for Lancer also
runs in the context of the new worker thread.

The ndo_set_rx_mode() and ndo_add/del_vxlan_port() calls may be called with
BHs disabled. The driver currently issues the required cmds to the FW in
these contexts and polls on completions from the FW, while BHs remain
disabled. This can cause either packet loss or packet reception to be
delayed on that CPU.
This patch defers processing of the above cmds to a separate workqueue.
With this change, FW cmds are now issued only in process context.
Now that the FW cmds are issued only in process context, they can sleep
waiting for a completion instead of polling. All the spin_lock_bh(mcc_lock)
calls are now replaced with mutex calls.
Also a new rx_filter_lock is now needed to protect the RX filtering fields

Eachtime the ndo_set_rx_mode() routine is called, the driver programs the
multicast list in the adapter without checking if there are any changes to
the list. This leads to a flood of RX_FILTER cmds when a number of vlan
interfaces are configured over the device, as the ndo_ gets
called for each vlan interface. To avoid this, we now use __dev_mc_sync()
and __dev_uc_sync() API, but only to detect if there is a change in the
mc/uc lists. Now that we use this API, the code has to be-designed to
issue these API calls for each invocation of the be_set_rx_mode() call.

The be2net driver performs fw temperature queries on be_worker() routine,
which is executed each second for each be_adapter. There is a frequency
threshold to avoid fw query to happens at each call to be_worker();
instead, currently a fw query occurs once in 64 runs of the procedure.
Nevertheless, this fw temperature query is invoked only for adapters which
interface is up, so we can see I/O errors on read of hwmon counters from
userspace (from tools like lm-sensors) in case we have adapters' functions
which interface is down.
This patch moves the fw query code to be invoked even if interface is down.

On SR-IOV profiles, when the user connects a Linux Bridge or OVS to a BE3
vport, they suffer the "broadcast/multicast echo" problem. BE3 EVB echoes
broadcast and multicast packets back to PF's vport confusing the
Linux bridge. BE3 relies on the src-mac addr being programmed on the
interface to avoid sending back an echo of a broadcast or multicast packet
on a vPort. When a Linux bridge is connected to a BE3, the mac-addr of the
VM behind the bridge doesn't get configured on the vPort and so echo
cancellation doesn't work.
This patch worksaround this problem by disabling the EVB initially
and re-enabling it *only* when SR-IOV is enabled by the user. For the
driver fix to work, the BE3 FW version must be >= 11.1.84.0.

Skyhawk does support wake-up from ACPI shutdown state - S5, provided the
platform supports it (like Auxiliary power source etc). The changes listed
below are done to fix this.
1) There's no need to defer the HW configuration of WOL to be_suspend().
Remove this in be_suspend() and move it to be_set_wol() ethtool function
so it is configured directly in the context of ethtool. This automatically
takes care of the shutdown case.
2) The driver incorrectly uses WOL_CAP field in the FW response to
get_acpi_wol_cap() command, to determine if WOL is enabled. Instead the
driver must rely on the macaddr field in the response to infer WOL state.
3) In be_get_config() during init, if we find that WOL is enabled in FW,
call pci_enable_wake() to enable pmcsr.pme_en bit. This is needed to
support persistent WOL configuration provided by the FW in some platforms.
4) Remove code in be_set_wol() that writes to PCICFG_PM_CONTROL_OFFSET
to set pme_en bit; pci_enable_wake() sets that.

When the interface is opened (in be_open()) the routine
be_enable_if_filters() must be called to switch on the basic filtering
capabilities of an interface that are not changed at run-time.
These include the flags UNTAGGED, BROADCAST and PASS_L3L4_ERRORS.
Other flags such as MULTICAST and PROMISC must be enabled later by
be_set_rx_mode() based on the state in the netdev/adapter struct.
be_enable_if_filters() routine is wrongly trying to enable MULTICAST flag
without checking the current adapter state. This can cause the RX_FILTER
cmds to the FW to fail. This patch fixes this problem by only enabling
the basic filtering flags in be_enable_if_filters().
The VF must be able to issue RX_FILTER cmd with any filter flag, as long
as the PF allowed those flags (if_cap_flags) in the iface it provisioned
for the VF. This rule is applicable even when the VF doesn't have the
FILTMGMT privilege. There is a bug in BE3 FW that wrongly fails RX_FILTER
multicast programming cmds on VFs that don't have FILTMGMT privilege.
This patch also helps in insulating the VF driver from be_open failures due
to the FW bug. A fix for the BE3 FW issue will be available in
versions >= 11.0.283.0 and 10.6.334.0

In QnQ configurations like Flex-10 where the VLANs are inserted by the
ASIC, on rare occasions the HW is encountering a scenario where the
final frame length ends to be greater than what the ASIC can support.
This is because when the TXULP pulls the TX WRB to check the length
of the frame to be transmitted it also adds the size of VLANs to be
inserted by the HW to the length of the frame indicated in the WRB,
which in some cases fails the range check. This causes a UE.

The VF link state setting transition from "disable" to "auto" does not work
due to a bug in SET_LOGICAL_LINK_CONFIG_V1 cmd in FW. This issue could not
be fixed in FW due to some backward compatibility issues it causes with
some released drivers. The issue has been fixed by introducing a new
version (v2) of the cmd from 10.6 FW onwards. In v2, to set the VF link
state to auto, both PLINK_ENABLE and PLINK_TRACK bits have to be set to 1.
The VF link state setting feature now works on Lancer chips too from
FW ver 10.6.315.0 onwards.

Recently Dough Ledford reported a deadlock happening
between ocrdma-load sequence and NetworkManager service
issueing "open" on be2net interface.
The deadlock happens when any be2net hook (e.g. open/close) is called
in parallel to insmod ocrdma.ko.
A. be2net is sending administrative open/close event to ocrdma holding
device_list_mutex. It does this from ndo_open/ndo_stop hooks of be2net.
So sequence of locks is rtnl_lock---> device_list lock
B. When new ocrdma roce device gets registered, infiniband stack now
takes rtnl_lock in ib_register_device() in GID initialization routines.
So sequence of locks in this path is device_list lock ---> rtnl_lock.
This improper locking sequence causes deadlock.
In order to resolve the above deadlock condition, ocrdma intorduced a
patch to stop listening to administrative open/close events generated from
be2net driver. It now depends on link-state-change async-event generated from
CNA. This change leaves behind dead code which used to generate administrative
open/close events. This patch cleans-up all that dead code from be2net.

NAPI drivers no longer need to observe a particular protocol
to benefit from busy polling (CONFIG_NET_RX_BUSY_POLL=y)
napi_hash_add() and napi_hash_del() are automatically called
from core networking stack, respectively from
netif_napi_add() and netif_napi_del()
This patch depends on free_netdev() and netif_napi_del() being
called from process context, which seems to be the norm.
Drivers might still prefer to call napi_hash_del() on their
own, since they might combine all the rcu grace periods into
a single one, knowing their NAPI structures lifetime, while
core networking stack has no idea of a possible combining.
Once this patch proves to not bring serious regressions,

The commit 435452aa88 ("Prevent VFs from enabling VLAN promiscuous mode")
fixed the PF driver to not include the VLAN promisc capability while
provisioning the interface for a VF. But the fix did not remove this
capability from the profile descriptor of the VF. This causes the VF
driver to request this capability when it tries to create it's interface
at probe time. This could potentailly cause the VF probe to fail if the
FW enforces strict checking of the flags based on what was provisoned
by the PF. This strict checking is not being done by FW currently but
will be fixed in a future version. This patch fixes this issue by updating
the VF's profile descriptor so that they match the interface capability
flags provisioned by the PF.

VxLAN offloading is not functional if the NIC is running in multichannel
mode (UMC, FLEX-10, VNIC...). Enabling this additionally kills whole
connectivity through the NIC and the device needs to be down and up to
restore it. The firmware should take care about it and does not allow
the conversion of interface to tunnel type (be_cmd_manage_iface) or should
support VxLAN offloading if multichannel config is enabled.
I have tested this on the latest available firmware (10.6.144.21).

sw1p1 << device side vlans (missing)
sw1p2 57
sw1p2

(When the port is bridged, the output repeats the vlan list for the vlans
on the bridge side of the port and the vlans on the device side of the
port. The listing above show no vlans for the device side even though they
are installed).
After this patch:
$ bridge -c vlan show

it has been well over a decade since I last updated it. And there is
no value in anyone else taking over updating it either.
However the references to it continue to spread as boiler plate text

da91309e0a (cpumask: Utility function to set n'th cpu...) created a
genuinely weird function. I never saw it before, it went through DaveM.
(He only does this to make us other maintainers feel better about our own
mistakes.)
cpumask_set_cpu_local_first's purpose is say "I need to spread things
across N online cpus, choose the ones on this numa node first"; you call
it in a loop.
It can fail. One of the two callers ignores this, the other aborts and
fails the device open.
It can fail in two ways: allocating the off-stack cpumask, or through a
convoluted codepath which AFAICT can only occur if cpu_online_mask
changes. Which shouldn't happen, because if cpu_online_mask can change
while you call this, it could return a now-offline cpu anyway.
It contains a nonsensical test "!cpumask_of_node(numa_node)". This was
drawn to my attention by Geert, who said this causes a warning on Sparc.
It sets a single bit in a cpumask instead of returning a cpu number,
because that's what the callers want.
It could be made more efficient by passing the previous cpu rather than
an index, but that would be more invasive to the callers.

The hwmon interface in the be2net driver causes a link error when
be2net is built-in while the hwmon subsystem is a loadable module:
drivers/built-in.o: In function `be_probe':
drivers/net/ethernet/emulex/benet/be_main.c:5761: undefined reference to `devm_hwmon_device_register_with_groups'
This adds a new Kconfig symbol, following the example of multiple
other drivers that have the same problem. The new CONFIG_BE2NET_HWMON
will not be available when (BE2NET=y && HWMON=m) to avoid this
problem.
We have to also mark be_hwmon_show_temp as 'static' to ensure the

OS2BMC feature will allow the server to communicate with the on-board
BMC/idrac (Baseboard Management Controller) over the LOM via
standard Ethernet.
When OS2BMC feature is enabled, the LOM will filter traffic coming
from the host. If the destination MAC address matches the iDRAC MAC
address, it will forward the packet to the NC-SI side band interface
for iDRAC processing. Otherwise, it would send it out on the wire to
the external network. Broadcast and multicast packets are sent on the
side-band NC-SI channel and on the wire as well. Some of the packet
filters are not supported in the NIC and hence driver will identify
such packets and will hint the NIC to send those packets to the BMC.
This is done by duplicating packets on the management ring. Packets
are sent to the management ring, by setting mgmt bit in the wrb header.
The NIC will forward the packets on the management ring to the BMC
through the side-band NC-SI channel.

is reported to the driver in the TX completion; this is reflected in the
