From f67d5271b0e828db67354bf3e0585c9d1565e731 Mon Sep 17 00:00:00 2001 From: rahnds Date: Fri, 31 Mar 2000 05:33:36 +0000 Subject: [PATCH] Revision 1.3 checked in again, version 1.4 was incorrectly checked in when if_gm.c was supposed to be checked in. It was a non-functional working version that has not yet been finished, it needs the bitbang mii code from NetBSD, or the proper routines imbedded in the driver. --- sys/arch/powerpc/mac/if_bm.c | 330 ++++++++++++++++------------------- 1 file changed, 146 insertions(+), 184 deletions(-) diff --git a/sys/arch/powerpc/mac/if_bm.c b/sys/arch/powerpc/mac/if_bm.c index c6f3cd4c101..18d183be4a0 100644 --- a/sys/arch/powerpc/mac/if_bm.c +++ b/sys/arch/powerpc/mac/if_bm.c @@ -1,8 +1,8 @@ -/* $OpenBSD: if_bm.c,v 1.4 2000/03/25 04:36:56 rahnds Exp $ */ -/* $NetBSD: if_bm.c,v 1.6 2000/02/02 17:09:43 thorpej Exp $ */ +/* $OpenBSD: if_bm.c,v 1.5 2000/03/31 05:33:36 rahnds Exp $ */ +/* $NetBSD: if_bm.c,v 1.1 1999/01/01 01:27:52 tsubai Exp $ */ /*- - * Copyright (C) 1998, 1999, 2000 Tsubai Masanari.
