[PATCH] Set the correct RTNL family for multicast netconf messages

From: Sven-Thorsten Dietrich
Date: Thu Jun 27 2013 - 19:45:00 EST


There may be other cases that require a special case, so I chose the switch approach.

Please note, that all other messages from ipmr[6].c correctly set the family, while these do not.

Thanks

Sven
