NetBSD/sys/dev/ic/i82595reg.h
is 95f41d24cc Add "iy" driver for Ethernet ISA boards using the Intel i82595 chip, e.g.
(and only tested on) Intel Etherexpress PRO. Should work on any i82595 ISA
board which uses an EEPROM for config information; NETBLKID not yet supported.
TODO: change to BUS interface, add multicast support.
