- 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.
Also make the interrupt handler for older 3com cards look like the xl one.
I.e. don't ack the interrupt latch bit before checking if it is set.
At the same time, introduce constants for the watched interrupts, so that
we don't copy them all over the place.
