Other protocols beside the networking driver need the ability
of passing some L2 traffic, usually [although not limited] for the

Introduce new rtnl UAPI that exposes a list of vlans per VF, giving
the ability for user-space application to specify it for the VF, as an
option to support 802.1ad.
We adjusted IP Link tool to support this option.
For future use cases, the new UAPI supports multiple vlans. For now we
limit the list size to a single vlan in kernel.
Add IFLA_VF_VLAN_LIST in addition to IFLA_VF_VLAN to keep backward
compatibility with older versions of IP Link tool.
Add a vlan protocol parameter to the ndo_set_vf_vlan callback.
We kept 802.1Q as the drivers' default vlan protocol.
Suitable ip link tool command examples:
Set vf vlan protocol 802.1ad:
ip link set eth0 vf 1 vlan 100 proto 802.1ad
Set vf to VST (802.1Q) mode:
ip link set eth0 vf 1 vlan 100 proto 802.1Q
Or by omitting the new parameter
ip link set eth0 vf 1 vlan 100

Commit fe56b9e6a8d95 ("qed: Add module with basic common support")
has introduced a stack corruption during probe, where filling a
local struct with data to be sent to management firmware is incorrectly
filled; The data is written outside of the struct and corrupts
the stack.

fdb dumps spanning multiple skb's currently restart from the first
interface again for every skb. This results in unnecessary
iterations on the already visited interfaces and their fdb
entries. In large scale setups, we have seen this to slow
down fdb dumps considerably. On a system with 30k macs we
see fdb dumps spanning across more than 300 skbs.
To fix the problem, this patch replaces the existing single fdb
marker with three markers: netdev hash entries, netdevs and fdb
index to continue where we left off instead of restarting from the
first netdev. This is consistent with link dumps.
In the process of fixing the performance issue, this patch also
re-implements fix done by
commit 472681d57a5d ("net: ndo_fdb_dump should report -EMSGSIZE to rtnl_fdb_dump")
(with an internal fix from Wilson Kok) in the following ways:
- change ndo_fdb_dump handlers to return error code instead
of the last fdb index
- use cb->args strictly for dump frag markers and not error codes.
This is consistent with other dump functions.
Below results were taken on a system with 1000 netdevs
and 35085 fdb entries:
before patch:
$time bridge fdb show | wc -l
15065
real 1m11.791s
user 0m0.070s
sys 1m8.395s
(existing code does not return all macs)
after patch:

Each VF employees a lock that's supposed to serialize its usage of the
HW channel for communication with its PF, but the critical section is
ill-defined:
- VFs currently release the lock whenever the PF response arrives,
prior to actually processing the reply buffer [which was also supposed
to have been protected by same lock].
- The lock would be released on first response, ignoring the possibilty
the sw flow isn't over [as might be the case of the acquisition flow].
As a result, the flow would run unprotected and would cause a double
mutex release [as the additional message completion would release it
while its actually already free].
Change the flow to have a dedicated function to be called at end of each
flow and release the lock.

Modern VFs can't run on old non-compatible as the fastpath HSI is
slightly changed - but as the HSI is actually very close [basically,
a single bit whose meaning flipped] this can be supported with small
modifications.
The major differences would be in:
- Recognizing that VF is running on top of a legacy PF.
- Returning some slowpath configurations that are no longer needed
on top of modern PFs, but would be required when working over
the legacy ones.

This new firmware for the qed* adpaters fixes several issues:
- Better blocking of malicious VFs.
- After FLR, Tx-switching [internal routing] of packets might
be incorrect.
- Deletion of unicast MAC filters would sometime have side-effect
of corrupting the MAC filters configred for a device.
It also contains fixes for future qed* drivers that *hopefully* would be
sent for review in the near future.
In addition, it would allow driver some new functionality, including:
- Allowing PF/VF driver compaitibility with old drivers [running
pre-8.10.5.0 firmware].
- Better debug facilities.
This would also bump the qed* driver versions to 8.10.9.20.

Driver uses netif_tx_queue_stopped() to make sure the xmit_more
indication will be honored, but that only checks for DRV_XOFF.
At the same time, it's possible that during transmission the DQL will
close the transmission queue with STACK_XOFF indication.
In re-configuration flows, when the threshold is relatively low, it's
possible that the device has no pending tranmissions, and during
tranmission the driver would miss doorbelling the HW.
Since there are no pending transmission, there will never be a Tx
completion [and thus the DQL would not remove the STACK_XOFF indication],
eventually causing the Tx queue to timeout.
While we're at it - also doorbell in case driver has to close the
transmission queue on its own [although this one is less important -
if the ring is full, we're bound to receive completion eventually,
which means the doorbell would only be postponed and not indefinetly
blocked].
