From 55c9adde13dfc6b738e0f70c071a0622e52f35ed Mon Sep 17 00:00:00 2001 From: Shirley Ma Date: Thu, 8 Mar 2007 14:59:30 -0800 Subject: IPoIB: Turn on interface's carrier after broadcast group is joined Do netif_carrier_on() right after the IPv4 broadcast multicast group is joined, rather than waiting for all of the initial set of multicast group joins to finish. This allows at least IPv4 traffic to limp along on broken fabrics where not all multicast groups can be joined.
