One more missing piece of the puzzle. Add vlan dump support to switchdev
port's bridge_getlink. iproute2 "bridge vlan show" cmd already knows how
to show the vlans installed on the bridge and the device , but (until now)
no one implemented the port vlan part of the netlink PF_BRIDGE:RTM_GETLINK
msg. Before this patch, "bridge vlan show":
$ bridge -c vlan show
port vlan ids
sw1p1 30-34 << bridge side vlans
57
sw1p1 << device side vlans (missing)
sw1p2 57
sw1p2
sw1p3
sw1p4
br0 None
(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
port vlan ids
sw1p1 30-34 << bridge side vlan
57
sw1p1 30-34 << device side vlans
57
3840 PVID
sw1p2 57
sw1p2 57
3840 PVID
sw1p3 3842 PVID
sw1p4 3843 PVID
br0 None
I re-used ndo_dflt_bridge_getlink to add vlan fill call-back func.
switchdev support adds an obj dump for VLAN objects, using the same
call-back scheme as FDB dump. Support included for both compressed and
un-compressed vlan dumps.

The patch fixes a bug in the default configuration which
prevented a software bridge loaded on the PF interface from
working correctly because broadcast packets are incorrectly
looped back.
Fix the general case, by loading the driver in VEPA mode Until a
VF or VMDq VSI is added. This way loopback on the Main VSI is
turned off until needed and can resolve the issue of unnecessary
reflection for users that do not have VF or VMDq VSIs setup.
The driver must now coordinate the loopback setting for the Flow
Director (FDIR) VSI to make sure it is in sync with the current
VEB or VEPA mode setting.
The user can still switch bridge modes from the bridge commands and
choose to be in VEPA mode with VF VSIs. Because of hardware
requirements, the call to switch to VEB mode when no VF/VMDqs are
present will be rejected.
NOTE: This patch uses BIT_ULL as that is preferred going forward,
a followup patch in the lower priority queue to net-next will fix
up the remaining 1 << usages.

Because i40e_fcoe_ctxt_eof should never be called without
i40e_fcoe_eof_is_supported being called first, the EOF in fcoe_ctxt_eof
should always be valid and therefore we do not need to print an error
if it is not valid.
However, a WARN ON to easily catch any calls to i40e_fcoe_ctxt_eof that
aren't preceded with a call to i40e_fcoe_eof_is_supported is helpful.

Gratuitously notify VFs of link state when they activate their queues.
In general, this is the last thing that a VF driver will do as it opens
its interface, so this is a good time to notify the VF.
Currently, VF devices assume link is up unless told otherwise, which
means that VFs instantiated on a PF with no link will report the wrong
state. This change corrects that issue.

Explicitly stop the rings belonging to each VF when disabling SR-IOV.
Even though the VFs were gone, and the associated VSIs were removed,
the rings were not stopped, and in some circumstances the hardware would
continue to access the memory formerly used by the rings, causing
memory corruption or DMAR errors, both of which would lead to general
malaise of the kernel.
To relieve this condition, explicitly stop all the rings associated with

This does not affect the Virtual channel API as such but it changes the
meaning of what is communicated to the VSI resource struct as vsi_id.
Earlier vsi_idx was being passed in, which was the index in the PF's VSI
array. Now we pass vsi_id as communicated by the FW to the driver.
This will help with future expansion of VF and FW communication.
With this in place now the VF and Virtual channel driver change to move over
to VSI id use is complete and is validated.
