From 3da889b616164bde76a37350cf28e0d17a94e979 Mon Sep 17 00:00:00 2001 From: stephen hemminger Date: Mon, 11 Mar 2013 13:52:17 +0000 Subject: [PATCH] bridge: reserve space for IFLA_BRPORT_FAST_LEAVE 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.
