Support HW offloaded filtering of MAC/VLAN packets. To allow that, we add a handler to handle VLAN configurations coming through the control VQ. Two operations are supported. 1. Adding VLAN - in this case, an entry will be added to the RX flow table that will allow the combination of the MAC/VLAN to be forwarded to the TIR. 2. Removing VLAN - will remove the entry from the flow table, effectively blocking such packets from going through. Currently the control VQ does not propagate changes to the MAC of the VLAN device so we always use the MAC of the parent device. Examples: 1. Create vlan device: $ ip link add link ens1 name ens1.8 type vlan id 8 Signed-off-by: Eli Cohen <elic@nvidia.com> Message-Id: <20220411122942.225717-4-elic@nvidia.com> Signed-off-by: Michael S.
