>Description:
	
	It would appear that the ex(4) driver does not always
	get the mac address right.  It can change from reboot
	to reboot.
>How-To-Repeat:

	
	install a 3c905 Rev B in a machine and build a kernel for it.
	boot it and notice an odd looking MAC address is displayed
	during autoconf.

	Below are some log messages showing how it continues to
	change time and time again.

	This is not the only time I have see this problem with
	ex(4), but this is the first time I *know* I have good
	hardware and as a result I am confident this is a bug.
