    Support to encoding decoding skb prio on IFE action · 200e10f4

        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
