[PATCH 3.2 090/106] rtnetlink: add IFLA_GROUP to ifla_policy

[Ben Hutchings]

3.2.93-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Serhey Popovych <serhe.popovych@xxxxxxxxx>

commit db833d40ad3263b2ee3b59a1ba168bb3cfed8137 upstream.

Network interface groups support added while ago, however
there is no IFLA_GROUP attribute description in policy
and netlink message size calculations until now.

Add IFLA_GROUP attribute to the policy.

Fixes: cbda10fa97d7 ("net_device: add support for network device groups")
