Roman Mashak	8f04748016	net sched actions: change IFE modules alias names ... Make style of module alias name consistent with other subsystems in kernel, for example net devices. Fixes: 084e2f6566 ("Support to encoding decoding skb mark on IFE action") Fixes: 200e10f469 ("Support to encoding decoding skb prio on IFE action") Fixes: 408fbc22ef ("net sched ife action: Introduce skb tcindex metadata encap decap") Signed-off-by: Roman Mashak <mrv@mojatatu.com> Signed-off-by: David S.

Jamal Hadi Salim	408fbc22ef	net sched ife action: Introduce skb tcindex metadata encap decap ... Sample use case of how this is encoded: user space via tuntap (or a connected VM/Machine/container) encodes the tcindex TLV. Sample use case of decoding: IFE action decodes it and the skb->tc_index is then used to classify. So something like this for encoded ICMP packets: .. first decode then reclassify... skb->tcindex will be set sudo $TC filter add dev $ETH parent ffff: prio 2 protocol 0xbeef \ u32 match u32 0 0 flowid 1:1 \ action ife decode reclassify ...next match the decode icmp packet... sudo $TC filter add dev $ETH parent ffff: prio 4 protocol ip \ u32 match ip protocol 1 0xff flowid 1:1 \ action continue ... last classify it using the tcindex classifier and do someaction.. sudo $TC filter add dev $ETH parent ffff: prio 5 protocol ip \ handle 0x11 tcindex classid 1:1 \ action blah..
