net/mlx5e: TC, Add offload support for trap with additional actions

Browse source

TC trap action offload is currently supported only when trap is the sole action
in the flow.

This patch remove this limitation by changing trap action offload to not use
MLX5_ATTR_FLAG_SLOW_PATH flag and instead set the flow destination table
explicitly to be the slow table. This will allow offload of the additional
actions.

TC flow example:
tc filter add dev $REP2 protocol ip prio 2 root \
	flower skip_sw dst_mac $mac0 \
	action mirred egress redirect dev $REP3 \
	action pedit ex munge eth dst set $mac2  pipe \
	action trap
