* Support to encoding decoding skb mark on IFE actionJamal Hadi Salim2016-03-011-0/+79
Example usage: Set the skb using skbedit then allow it to be encoded sudo tc qdisc add dev $ETH root handle 1: prio sudo tc filter add dev $ETH parent 1: protocol ip prio 10 \ u32 match ip protocol 1 0xff flowid 1:2 \ action skbedit mark 17 \ action ife encode \ allow mark \ dst 02:15:15:15:15:15 Note: You dont need the skbedit action if you are already encoding the skb mark earlier. A zero skb mark, when seen, will not be encoded. Alternative hard code static mark of 0x12 every time the filter matches sudo $TC filter add dev $ETH parent 1: protocol ip prio 10 \ u32 match ip protocol 1 0xff flowid 1:2 \ action ife encode \ type 0xDEAD \ use mark 0x12 \ dst 02:15:15:15:15:15 Signed-off-by: Jamal Hadi Salim <jhs@mojatatu.com> Acked-by: Cong Wang <xiyou.wangcong@gmail.com> Signed-off-by: David S.
