Subject: [PATCH net-next] net/mlx5e: avoid check the hw_stats of flow_action for FT flow

From: wenxu <wenxu@...oud.cn>

The hw_stats in flow_action can't be supported in nftable
flowtables. This check will lead the nft flowtable offload
failed. So don't check the hw_stats of flow_action for FT
flow.
