$ tc filter add dev enp130s0f0 protocol ip prio 1 root flower skip_sw dst_ip 11.12.13.14 action mirred egress redirect dev enp130s0f0 Error: mlx5_core: devices are both uplink, can't offload forwarding. $ tc filter add dev enp130s0f0 protocol ip prio 1 parent ffff: flower skip_sw dst_ip 11.12.13.14 action mirred egress redirect dev enp130s0f0 Error: mlx5_core: devices are both uplink, can't offload forwarding. The firmware used doesn't support that feature? https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/?id=613f53fe09a27f928a7d05132e1a74b5136e8f04 -- Best regards, Tonghao
