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")

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..
