[Xen-devel] PATCH: Multicast support for linux-2.6.16-xen

[Christophe Devriese <christophe.devriese@xxxxxxxx>]

I would really like this patch to be merged in. Linux's bridging code treats 
multicasts as broadcasts, so this very simple code enables linux to run stuff 
like vrrpd inside xen, allowing various kinds of failover scenarios not 
possible without this patch.

diff netfront.c netfront-new.c

> static void network_set_multicast_list(struct net_device *dev) {
