Today, I check in changes to the GEM driver which makes the multicast filter
work and it now properly comes when plugged into a GigE switch.  The GEM
in the SunBlade 100 also negotiates correctly with a NetGear FS108 Hub.
Hopefully, soon I'll be able to make Sun PCI 1000SX card work as well.

At this time, I think macppc should switch to gem and move gm into the
Attic.
