3.11.10.11 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Toshiaki Makita <makita.toshi...@lab.ntt.co.jp> commit 30313a3d5794472c3548d7288e306a5492030370 upstream. When bridge device is created with IFLA_ADDRESS, we are not calling br_stp_change_bridge_id(), which leads to incorrect local fdb management and bridge id calculation, and prevents us from receiving frames on the bridge device.
