System: NetBSD plucky 1.4.1 NetBSD 1.4.1 (STDILX) #0: Mon Nov 15 13:53:22 EST 1999 pjl@brookside:/usr/src/sys-1.4.1/arch/i386/compile/STDILX i386


	The ZNYX quad-port ethernet card, which is listed as
supported, and registers as 4 'de' Digital 21140 ports, does not
register full-duplex as an option, nor does it properly auto-negotiate
against a switch. This card does work under Solaris/x86 and Windows in
full-duplex properly.

	Plug a port into a fast ethernet switch
	Watch the collisions.
	A bypass is to hard-code the port on the switch side, but
that's not exactly accessible thru NetBSD.
	ZNYX does provide its own driver, with additional
functionality, for FreeBSD in object form. Perhaps some proding could
be done?
