/* $NetBSD: if_levar.h,v 1.5 1997/06/06 23:48:03 thorpej Exp $ */
Make the MI LANCE driver standalone, and use cfattach to resolve naming conflicts between bus attachments on ports that can have multiple instances of the LANCE. Add a real PCI front-end for PCnet-PCI Ethernet cards. Changed struct ifnet to have a pointer to the softc of the underlying device and a printable "external name" (name + unit number), thus eliminating if_name and if_unit. Updated interface to (*if_watchdog)() and (*if_reset)() to take a struct ifnet *, rather than a unit number.

New ARP system, supports IPv4 over any hardware link. Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will only support Ethernet. Tcpdump itself should be ok, but libpcap needs lot of work. For the detailed change history, look at the commit log entries for the is-newarp branch.

New bus.h implementation/interface: - No more distinction between i/o-mapped and memory-mapped devices. It's all "bus space" now, and space tags differentiate the space with finer grain than the bus chipset tag. - Add memory barrier methods. - Implement space alloc/free methods. - Implement region read/write methods (like memcpy to/from bus space). This interface provides a better abstraction for dealing with machine-independent chipset drivers.
