Thanks! I noticed that 'ip maddr' did not include the new address and
drop membership in the end was failing, but I was just too lazy to look
at what was causing this yesterday..

Well, almost ;-). This works around it by making sure we always end up
using SIOCADDMULTI..

I removed that if statement which was always false due to drv structure
being zeroed just couple of lines above this piece of code.. This fixed
the problem and rest of the patch was fine and made the address adding
work fine with PACKET_ADD_MEMBERSHIP. This is in CVS now.
