From 3170a4a6dfccc544dc14d384eebcbea138fb1a3f 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.
