From 6c40999ef70be26cc633e9dc0ff8c3c95401849a Mon Sep 17 00:00:00 2001 From: Sepherosa Ziehau Date: Sat, 18 Nov 2006 04:13:39 +0000 Subject: [PATCH] Properly setup Link/Act LED for rt2x61 chips. LED EEPROM configures and LED MCU data/command layout are obtained from Linux RT61 driver (the reference driver?). # This makes my Edimax EW-7608PG(rt2661d) LED shining as expected. --- sys/dev/netif/ral/rt2661.c | 85 ++++++++++++++++++++++++++++++++++- sys/dev/netif/ral/rt2661reg.h | 31 ++++++++++++- sys/dev/netif/ral/rt2661var.h | 3 +- 3 files changed, 115 insertions(+), 4 deletions(-) diff --git a/sys/dev/netif/ral/rt2661.c b/sys/dev/netif/ral/rt2661.c index a4b30b5157..a50765edda 100644 --- a/sys/dev/netif/ral/rt2661.c +++ b/sys/dev/netif/ral/rt2661.c @@ -15,7 +15,7 @@ * OR IN CONNECTION WITH THE USE OR PERFORMANCE OF THIS SOFTWARE. * * $FreeBSD: src/sys/dev/ral/rt2661.c,v 1.4 2006/03/21 21:15:43 damien Exp $ - * $DragonFly: src/sys/dev/netif/ral/rt2661.c,v 1.4 2006/10/25 20:55:58 dillon Exp $ + * $DragonFly: src/sys/dev/netif/ral/rt2661.c,v 1.5 2006/11/18 04:13:39 sephe Exp $ */ /* @@ -64,7 +64,7 @@ #ifdef RAL_DEBUG #define DPRINTF(x) do { if (ral_debug > 0) printf x;
