Recently we added a new option, SKBMOD_F_ECN, to tc-skbmod(8). Add a control-plane selftest for it.

Depends on kernel patch "net/sched: act_skbmod: Add SKBMOD_F_ECN option support", as well as iproute2 patch "tc/skbmod: Introduce SKBMOD_F_ECN option".

Reviewed-by: Cong Wang cong.wang@bytedance.com Signed-off-by: Peilin Ye peilin.ye@bytedance.com --- Hi all,

The corresponding iproute2-next patch is here: https://lore.kernel.org/netdev/20210721232053.39077-1-yepeilin.cs@gmail.com/

Thanks, Peilin Ye
