patch adds support for the Linksys 10/100 PCMCIA card
if you have a NE2000 type card which is supported by if_ed.c, please
apply this patch and provide feedback. it work wonderfully for me,
but i have only two cards that use this driver.....there are a wide
variety of cards that use the if_ed.c driver. i want to make sure of
the change before committing it.
