Call for testers: patch for the dc(4) driver

	Hi guys,



I need people to give this patch a try and see if it doesn't break
anything.  It shouldn't cause any harm, but better safe than sorry.
This patch allows the dc(4) driver to properly read the MAC address in
the EEPROM on FreeBSD/powerpc.  Andrew Gallatin tested it successfully
on his G4.  I'm particularly interested about people using dc(4) on
sparc64 since this arcihtecture is big endian.

Cheers,
Maxime
