Poking around with the configuration program of our ethernet cards
(NE2000 clones manufactured by Trust), I found out that they have a mode
(called NE2000 plus) in which they apparently use shared memory (at
least, the setup menu asks you to select a memory address.

Is this mode supported by the current if_ed driver, and is it documented
anywhere ? (I am asking because I remember discussion on the relative
performance of WD80x3 -- better, using shared memory -- and NE2000 --
slower, with programmed IO)

	Thanks
	Luigi
