Subject: [PATCH 4.1 153/159] bridge: netlink: account for the IFLA_BRPORT_PROXYARP_WIFI attribute size and policy

4.1-stable review patch.  If anyone has any objections, please let me know.

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

From: Nikolay Aleksandrov <nikolay@...ulusnetworks.com>

[ Upstream commit 786c2077ec8e9eab37a88fc14aac4309a8061e18 ]

The attribute size wasn't accounted for in the get_slave_size() callback
(br_port_get_slave_size) when it was introduced, so fix it now. Also add
a policy entry for it in br_port_policy.
