From ea2b26e0a0264650e13acac8e66d315bb818897c Mon Sep 17 00:00:00 2001 From: James Ketrenos Date: Wed, 24 Aug 2005 21:25:16 -0500 Subject: [PATCH] Catch ipw2200 up to equivelancy with v1.0.1 This commit contains the following fixes: Fixed #559: iwconfig rate support (thanks to Florian Hackenberger) Improved link signal quality calculation (thanks to Bill Moss) Fixed a problem with sensitivity threshold during association Added iwpriv for turning forcing long preamble support: % iwpriv eth1 set_preamble 1|0 Fixed #542 and #377 support for short preamble Fixed locked BSSID reporting channel number (thanks to Pedro Ramalhais) Fixed type-o with scan watchdog timeout message (thanks to Pedro Ramalhais) Changed logic for displaying get_mode output so the code is easier to follow (thanks to Pedro Ramalhais) Added initial support for WPA (thanks to Yi Zhu) -- tested with wpa_supplicant (either tip w/ ipw driver, or with -Dipw2100) with both CCMP and TKIP Fixed problem with CCMP not working due to uninitialized 802.11 header fields (thanks to Pedro Ramalhais) Bug references are to defects stored on http://bughost.org Signed-off-by: James Ketrenos --- drivers/net/wireless/ipw2200.c | 1694 +++++++++++++++++++++++--------- drivers/net/wireless/ipw2200.h | 23 +- 2 files changed, 1247 insertions(+), 470 deletions(-) diff --git a/drivers/net/wireless/ipw2200.c b/drivers/net/wireless/ipw2200.c index 3db0c32afe82..ddbee3edcd8c 100644 --- a/drivers/net/wireless/ipw2200.c +++ b/drivers/net/wireless/ipw2200.c @@ -32,7 +32,7 @@ #include "ipw2200.h" -#define IPW2200_VERSION "1.0.0" +#define IPW2200_VERSION "1.0.1" #define DRV_DESCRIPTION "Intel(R) PRO/Wireless 2200/2915 Network Driver" #define DRV_COPYRIGHT "Copyright(c) 2003-2004 Intel Corporation" #define DRV_VERSION IPW2200_VERSION @@ -44,7 +44,6 @@ MODULE_LICENSE("GPL");
