[PATCH v2 net-next 4/4] net: ipvlan: call netdev_lockdep_set_classes()

[Eric Dumazet]

In case a qdisc is used on a ipvlan device, we need to use different
lockdep classes to avoid false positives.

Fixes: f9eb8aea2a1e ("net_sched: transform qdisc running bit into a seqcount")
Fixes: 79640a4ca695 ("net: add additional lock to qdisc to increase throughput")
