[PATCH v2 iproute2 0/3] ip link: add support for network device groups

[Vlad Dogaru <ddvlad@rosedu.org>]

This patch series adds userspace support for network device groups.
There is support for setting device groups, listing only interfaces of a
specific group, and setting basic device parameters for all interfaces
in a group.

The patches use the IFLA_GROUP attribute, for which I posted pathes in a
different set.

Changes since version 1:
 * a single attribute is used for both setting the group of a device and
   manipulating an entire group.
