I have switched to 8-STABLE. Kernel does not seem to crash anymore, however IGMP still does not work. tcpdump complains that outgoing IGMP report and leave packets have incorrect checksum- it is always 0. Though I'm not sure weather it is IGMP checksum or IP checksum that is incorrect. 2009/12/7 Bruce Simpson <bms@incunabulum.net>: > Andriy Syrovenko wrote: >> >> Is it planned to be MFCed to STABLE? >> Or, could you possibly point me into the right revision in HEAD, so I >> could merge and test it locally? >> > > Actually I did already MFC most of my changes to stable/8, just not > releng/8.0. > > There were a few things to do with IGMP packet checks which I rolled in to > my last swathe of changes.
