	default y
	help
	  mlx5 ConnectX offloads support for TC classifier action (NET_CLS_ACT),
	  works in both native NIC mode and Switchdev SRIOV mode.
	  Actions get attached to a Hardware offloaded classifiers and are
	  invoked after a successful classification. Actions are used to
	  overwrite the classification result, instantly drop or redirect and/or
	  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.
	  If unsure, set to Y

config MLX5_TC_CT
