Drivers may not be able to implement a VLAN addition or reconfiguration.
In those cases it's desirable to explain to the user that it was

To that end, add extack argument to ndo_bridge_setlink. Adapt all users

Following patches will use the new argument in the bridge driver.

While reviewing code, I noticed that Eric Dumazet recommends that
drivers check the return code of napi_complete_done, and use that
to decide to enable interrupts or not when exiting poll. One of
the Intel drivers was already fixed (ixgbe).
Upon looking at the Intel drivers as a whole, we are handling our
polling and NAPI exit in a few different ways based on whether we
have multiqueue and whether we have Tx cleanup included. Several
drivers had the bug of exiting NAPI with return 0, which appears
to mess up the accounting in the stack.
Consolidate all the NAPI routines to do best known way of exiting
and to just mostly look like each other.
1) check return code of napi_complete_done to control interrupt enable
2) return the actual amount of work done.
3) return budget immediately if need NAPI poll again
Tested the changes on e1000e with a high interrupt rate set, and
it shows about an 8% reduction in the CPU utilization when busy
polling because we aren't re-enabling interrupts when we're about
to be polled.

40GbE Intel Wired LAN Driver Updates 2018-11-14
This series contains updates to i40e and virtchnl.
Lance Roy updates i40e to use lockdep_assert_held() instead of
spin_is_locked(), since it is better suited to check locking
requirements.
Jan improves the code readability in XDP by adding the use of a local
variable. Provides protection on methods that create/modify/destroy
VF's via locking mechanism to prevent unstable behaviour and potential
kernel panics.
Krzysztof adds a hardware capability flag to indicate whether firmware
supports stopping the LLDP agent.
Patryk replaces the use of strncpy() with strlcpy() to ensure the buffer
is NULL terminated.
Mitch fixes the issue of trying to start nway on devices that do not
support auto-negotiation, by checking the autoneg state before
attempting to restart nway.
Alice updates virtchnl to keep the checks all together for ease of
readability and consistency. Also fixed a "off by one" error in the
number of traffic classes being calculated.
Richard fixed VF port VLANs, where the priority bits were incorrectly
set because the incorrect shift and mask bits were being used.
Alan adds a bit to set and check if a timeout recovery is already
pending to prevent overlapping transmit timeout recovery.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
If a TX hang occurs, we attempt to recover by incrementally resetting.
If we're starved for CPU time, it's possible the reset doesn't actually
complete (or even fire) before another tx_timeout fires causing us to
fly through the different resets without actually doing them.
This adds a bit to set and check if a timeout recovery is already
pending and, if so, bail out of tx_timeout. The bit will get cleared at
the end of i40e_rebuild when reset is complete.

The i40e driver complains about unprivileged VFs trying to configure
promiscuous mode each time a VF reset occurs. This isn't the fault of
the poor VF driver - the PF driver itself is making the request.
To fix this, skip the privilege check if the request is to disable all
promiscuous activity. This gets rid of the bogus message, but doesn't
affect privilege checks, since we really only care if the unprivileged
VF is trying to enable promiscuous mode.

Previous to this commit the driver was immediately stopping Tx/Rx
queues when doing the following "echo 0 > sriov_numvfs" and then it was
calling pci_disable_sriov if the VFs are not assigned. This was causing
the VIRTCHNL_OP_DISABLE_QUEUES to fail because it was trying to stop
the queues for a second time.
Fix this by calling pci_disable_sriov before stopping the Tx/Rx queues.
This allows the VIRTCHNL_OP_DISABLE_QUEUES to get processed before the
driver tries to stop the Rx/Tx queues in ice_free_vfs.

Before releasing the VSI, remove the VSI scheduler node. If not,
the node is left in the scheduler tree and, on subsequent load, the
scheduler tree contains the node so it does not set it in vsi_ctx.
