Merge branch 'sfc-rx-vlan-filtering'

Edward Cree says:

====================
sfc: RX VLAN filtering

Adds support for VLAN-qualified receive filters on EF10 hardware.
This is needed when running as a guest if the hypervisor has enabled
vfs-vlan-restrict, in which case the firmware rejects filters not qualified
with VLAN 0.
