net/mlx5: VLAN push on RX, pop on TX
Some older NIC hardware isn't capable of doing VLAN push on RX and pop
on TX.
A workaround has been added in software to support it, but it has a
performance penalty since it requires a hairpin + loopback.
There's no such limitation with the newer NICs, so no need to pay the
price of the w/a. With this change the software w/a is disabled for
certain HW versions and steering modes that support it.
