net/mlx5e: Set vlan masks for all offloaded TC rules

Browse source

In flow steering, if asked to, the hardware matches on the first ethertype
which is not vlan. It's possible to set a rule as follows, which is meant
to match on untagged packet, but will match on a vlan packet:
    tc filter add dev eth0 parent ffff: protocol ip flower ...

To avoid this for packets with single tag, we set vlan masks to tell
hardware to check the tags for every matched packet.
