You need -CURRENT for the dc(4) driver to have a chance to work on
sparc64.  I have converted it to the busdma and made it endian-clean
after 5.1-RELEASE, and without these modifications it has 0 chances of
working, hence why it wasn't included in 5.1-RELEASE GENERIC kernel.

You'll still have the MAC address problem though.  That should be fixed
hopefully sometime soon.
