net/sched: act_sample: don't push mac header on ip6gre ingress
current 'sample' action doesn't push the mac header of ingress packets if they are received by a layer 3 tunnel (like gre or sit); but it forgot to check for gre over ipv6, so the following script: # tc q a dev $d clsact # tc f a dev $d ingress protocol ip flower ip_proto icmp action sample \ > group 100 rate 1 # psample -v -g 100 dumps everything, including outer header and mac, when $d is a gre tunnel over ipv6. Fix this adding a missing label for ARPHRD_IP6GRE devices. Fixes: 5c5670fa ("net/sched: Introduce sample tc action") Signed-off-by:Davide Caratti <dcaratti@redhat.com> Reviewed-by:
