Merge branch 'bpf-updates'
Daniel Borkmann says:
====================
BPF updates
Some minor updates to {cls,act}_bpf to retrieve routing realms
and to make skb->priority writable.
Thanks!
v1 -> v2:
- Dropped preclassify patch for now from the series as the
rest is pretty much independent of it
- Rest unchanged, only rebased and already posted Acked-by's kept
====================
