Merge branch 'pktdiag'
Nicolas Dichtel says:
====================
The goal of this patchset is to be able to get all infos exported via the
/proc/net/packet and also beeing able to get filter associated to af_packet
sockets.
As usual, the patch against iproute2 will be sent once the patches are included
and net-next merged. I can send it on demand.
