net/mlx5e: CT: Introduce connection tracking
Add support for offloading tc ct action and ct matches.
We translate the tc filter with CT action the following HW model:
+-------------------+ +--------------------+ +--------------+
+ pre_ct (tc chain) +----->+ CT (nat or no nat) +--->+ post_ct +----->
+ original match + | + tuple + zone match + | + fte_id match + |
+-------------------+ | +--------------------+ | +--------------+ |
v v v
set chain miss mapping set mark original
set fte_id set label filter
set zone set established actions
set tunnel_id do nat (if needed)
do decap
