From fd4c742d7c4932e37fc56914c4586327816df12e Mon Sep 17 00:00:00 2001 From: Eli Cohen Date: Tue, 17 Oct 2006 16:23:25 -0700 Subject: [PATCH] [PATCH] IPoIB: Rejoin all multicast groups after a port event When ipoib_ib_dev_flush() is called because of a port event, the driver needs to rejoin all multicast groups, since the flush will call ipoib_mcast_dev_flush() (via ipoib_ib_dev_down()). Otherwise no (non-broadcast) multicast groups will be rejoined until the networking core calls ->set_multicast_list again, and so multicast reception will be broken for potentially a long time.
