From 22319bbae1e450b43d55da545c44d05e84b78c6a Mon Sep 17 00:00:00 2001 From: hauke Date: Wed, 18 Mar 2009 22:22:57 +0000 Subject: [mac80211] Update compat-wireless to 2009-03-18 Removing of include/net/ieee80211_radiotap.h is not needed, because it is only used by this compat-wireless. There are changes in that file and compat-wireless needs the newest version. Some more symbols are deactivated in the default config file, this will make building faster. The rt2800pci patches are up to date now. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@14946 3c298f89-4303-0410-b956-a3cf2f4a3e73 --- .../mac80211/patches/202-ath5k_txpower_2413.patch | 672 --------------------- 1 file changed, 672 deletions(-) delete mode 100644 package/mac80211/patches/202-ath5k_txpower_2413.patch (limited to 'package/mac80211/patches/202-ath5k_txpower_2413.patch') diff --git a/package/mac80211/patches/202-ath5k_txpower_2413.patch b/package/mac80211/patches/202-ath5k_txpower_2413.patch deleted file mode 100644 index ddecd9e07..000000000 --- a/package/mac80211/patches/202-ath5k_txpower_2413.patch +++ /dev/null @@ -1,672 +0,0 @@ -Implement the power curve interpolation, which is required for -proper tx on 2413 and newer RF designs. - -Signed-off-by: Felix Fietkau - ---- a/drivers/net/wireless/ath5k/phy.c -+++ b/drivers/net/wireless/ath5k/phy.c -@@ -4,6 +4,7 @@ - * Copyright (c) 2004-2007 Reyk Floeter - * Copyright (c) 2006-2009 Nick Kossifidis - * Copyright (c) 2007-2008 Jiri Slaby -+ * Copyright (c) 2008-2009 Felix Fietkau - * - * Permission to use, copy, modify, and distribute this software for any - * purpose with or without fee is hereby granted, provided that the above -@@ -1438,31 +1439,449 @@ unsigned int ath5k_hw_get_def_antenna(st - */ - - /* -- * Initialize the tx power table (not fully implemented) -+ * find the lower and upper index of the values in the table surrounding the target value - */ --static void ath5k_txpower_table(struct ath5k_hw *ah, -- struct ieee80211_channel *channel, s16 max_power) -+static void -+ath5k_get_table_index(const u16 *tbl, unsigned int tbl_sz, u16 target, -+ unsigned int idx[2]) - { -- unsigned int i, min, max, n;
