+ mlx5 ConnectX offloads support for TC classifier action (NET_CLS_ACT),

+ Actions get attached to a Hardware offloaded classifiers and are

+ reformat packets in wire speeds without involving the host cpu.

+ If set to N, TC offloads in both NIC and switchdev modes will be disabled.

Say Y here if you want to support offloading connection tracking rules
