Subject: [PATCH net-next v2 0/5] sock_diag: monitor packet sockets

The goal of this patchset is to be able to monitor packet sockets.
The two first patches add new attributes for packet_diag subsystem, so that all
information exported via the /proc/net/packet are also exported via netlink.
The third patch allows the user to get details about filter attached to a packet
socket.
Then, the two last one enable sockets monitoring. A netlink message is sent each
time a packet socket is created, deleted or when the filter information are
updated.

As usual, the patch against iproute2 will be sent once the patches are included
and net-next merged. I can send it on demand.
With this serie, the tools ss can monitor packet sockets activity.

v2: add sock_diag_notify_del() to avoid confusion of the meaning of the second
    arg of __sock_diag_notify()
    enhance commitlog of patch 3/5
