>Description:

When I install my newest 3Com Etherlink III PCMCIA card, NetBSD probes
the MAC address as ff:fc:4b:a0:36:ca.  It should be 00:10:4b:a0:36:ca;
the first two octets are wrong.  Win95 finds the correct MAC address, so
it is not a hardware problem.

Note that TCP/IP works with the invalid MAC address except that "ff:*"
is a multicast address.  Many routers will not send to hosts with such
an address.

This card is a 3C589D.  I've have 3C589[ABC]s work fine on this laptop.
I wish 3Com would stop changing things randomly.

Here are the boot messages:

pcmcia1 at pcic0 controller 0 socket 1

>How-To-Repeat:

Insert a 3C589D into a pcmcia slot.  Boot under NetBSD.  Curse 3Com and
the horse they rode in on.
