Subject: bridge: reserve space for IFLA_BRPORT_FAST_LEAVE
From: stephen hemminger <stephen@xxxxxxxxxxxxxxxxxx>
[ Upstream commit 3da889b616164bde76a37350cf28e0d17a94e979 ]
The bridge multicast fast leave feature was added sufficient space
was not reserved in the netlink message. This means the flag may be
lost in netlink events and results of queries.
Found by observation while looking up some netlink stuff for discussion with Vlad.
Problem introduced by commit c2d3babfafbb9f6629cfb47139758e59a5eb0d80
