- Handle IFF_ALLMULTI case correctly. This is necessary to mrouted working. Tested by taca@netbsd.org. - Clear unnecessary multicast hash bit. Otherwise, unnecessary multicast packet is received. Tested by me with the 3C905C bought at akihabara. It was 2980yen. The code is written by fvdl@netbsd.org and me.
