I have just started to play with IPv6, and after trying to autoconfigure
the laptop's xe0 interface without any success, I found that the ICMPv6
route advertisements (which travel encapsulated into multicast Ethernet
frames, with dst address 33:33:0:0:0:1) were not being received by the
interface. However, a "netstat -a" shows clearly that multicast address:

Name  Mtu   Network       Address            Ipkts Ierrs    Opkts Oerrs  Coll
xe0   1500  <Link#2>    00:10:a4:e8:6f:b6     3199     0       24     8     0
                        33:33:e6:ef:ce:85
                        33:33:0:0:0:1
                        33:33:ff:e8:6f:b6
                        1:0:5e:0:0:1

The xe card, however, sends multicast ethernet frames without any problem.

Then, I used another PCMCIA ethernet card (a NE2000 clone) and everything
worked fine. Obviously something is seriously broken in the xe(4) driver
or in the xe hardware. BTW, the card is a Xircom RealPort 100 (equivalent
to the CE3-10/100).

Some xe(4) guru out there?

  Cheers,
  JMA
