Submitted by: Add the 3com 3C507 card to the if_ie.c driver. The files elink.c and elink.h are helding routines that are shared between the 3C507 and the 3C509/3C579. if_ie507.h are constant declarations unique to the 3C507. The code is based on the NetBSD driver if_ie.c donated to NetBSD by Rafal Boni and then modified by Charles Hannum.
