net/mlx5e: Add flow steering DMAC trap rule

Browse source

Add flow group to the L2 table to hold the catch-all DMAC rule. Add API
which adds/removes DMAC trap rule. This rule catches packets that were
destined to be dropped due to no-match with previous DMAC rules. The
trap rule steer these packets to the trap tir related to the trap-RQ.
