Example usage:
Set the skb priority 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 prio 17 \
action ife encode \
allow prio \
dst 02:15:15:15:15:15
Note: You dont need the skbedit action if you are already encoding the
skb priority earlier. A zero skb priority will not be sent
Alternative hard code static priority of decimal 33 (unlike skbedit)
then 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 prio 33 \
use mark 0x12 \
dst 02:15:15:15:15:15
