From 045a100420014f6185de39a421417b34a4cd4355 Mon Sep 17 00:00:00 2001 From: thorpej Date: Mon, 10 Aug 1998 23:59:58 +0000 Subject: [PATCH] Adapt to the new MII layer. This PHY driver now properly supports 802.3u autonegotiation, and will report the precise media selected by autonegotiation by reading PHY-specific registers. XXX There is still some work to do wrt. autonegotiation and the BNC/AUI support in the ThunderLAN PHY. --- sys/dev/mii/tlphy.c | 488 ++++++++++++++++++++-------- sys/dev/mii/{tlphy.h => tlphyreg.h} | 42 ++- sys/dev/mii/tlphyvar.h | 58 ++++ 3 files changed, 430 insertions(+), 158 deletions(-) rename sys/dev/mii/{tlphy.h => tlphyreg.h} (64%) create mode 100644 sys/dev/mii/tlphyvar.h diff --git a/sys/dev/mii/tlphy.c b/sys/dev/mii/tlphy.c index b4cff096931d..4178a92993ad 100644 --- a/sys/dev/mii/tlphy.c +++ b/sys/dev/mii/tlphy.c @@ -1,5 +1,42 @@ -/* $NetBSD: tlphy.c,v 1.6 1998/06/09 07:30:44 thorpej Exp $ */ - +/* $NetBSD: tlphy.c,v 1.7 1998/08/10 23:59:58 thorpej Exp $ */ + +/*- + * Copyright (c) 1998 The NetBSD Foundation, Inc. + * All rights reserved. + * + * This code is derived from software contributed to The NetBSD Foundation + * by Jason R.
