>Description:
	After attach, the adapter hardware is reset but the IFF_RUNNING flag
stays. This makes a simple "up" request (SIOCSIFFLAGS ioctl) fail.
(Most users set an address with "ifconfig". This does not trigger this bug.
Machines with NFS root are affected.)
>How-To-Repeat:
	Try root on nfs with a 3c590.
>Fix:
