net/mlx5e: Don't match on vlan non-existence if ethertype is wildcarded

Browse source

[ Upstream commit d3a80bb5a3 ]

For the "all" ethertype we should not care whether the packet has
vlans. Besides being wrong, the way we did it caused FW error
for rules such as:

tc filter add dev eth0 protocol all parent ffff: \
	prio 1 flower skip_sw action drop

b/c the matching meta-data (outer headers bit in struct mlx5_flow_spec)
wasn't set. Fix that by matching on vlan non-existence only if we were
also told to match on the ethertype.

Fixes: cee2648762 ('net/mlx5e: Set vlan masks for all offloaded TC rules')
