[SOLVED] Post Newton to Ocata upgrade jumbo frame MTU isn't set by neutron linuxbridge agent

After upgrading from Newton to Ocata my agent's wouldn't set mtu 9000 on the tap interfaces of my vm's.  I asked around in IRC after unsuccessful googling and haleyb suggested a couple of recent backports. and

After downloading the patch files and patching with patch -p1 -d /usr/lib/python2.7/site-packages --verbose < 46e6dd57.diff it started working again.  I'm not entirely sure if it was both patches or just the simple order of operation patch that fixed it.  Either way problem solved for now.
