net/sched: act_skbmod: Skip non-Ethernet packets
Currently tcf_skbmod_act() assumes that packets use Ethernet as their L2
protocol, which is not always the case. As an example, for CAN devices:
$ ip link add dev vcan0 type vcan
$ ip link set up vcan0
$ tc qdisc add dev vcan0 root handle 1: htb
$ tc filter add dev vcan0 parent 1: protocol ip prio 10 \
matchall action skbmod swap mac
Doing the above silently corrupts all the packets. Do not perform skbmod
actions for non-Ethernet packets.
Fixes: 86da71b57383 ("net_sched: Introduce skbmod action")
