[PATCH v2 0/2] net: add device groups

This patchset implements network device grouping and simple manipulation
of groups. Netlink has been updated to provide group information and
means of applying changes to members of a specific group via a single
message.

I will follow up with a patchset which updates iproute2 to use the new
parameters.

Changes since version 1:
 * we avoid adding a new attribute type by using the following
   convention: if no device name is specified, the interface index is
   negative, and there is a group specified, we change parameters for
   the whole group.
 * the dummy module is no longer modified to include an initial group
   for the devices it creates. The user is responsible for moving them
   to a different group by means of the provided netlink interface.
