net/mlx5e: Set vlan masks for all offloaded TC rules
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.
Fixes: 095b6cfd69ce ('net/mlx5e: Add TC vlan match parsing')
