From c580f67fd7fa9deee1f4cf6b86c694b880534a82 Mon Sep 17 00:00:00 2001 From: Zhu Yi Date: Mon, 21 Aug 2006 11:37:01 +0800 Subject: [PATCH] [PATCH] ipw2200: SIOCGIWFREQ ioctl returns frequency rather than channel The SIOCGIWFREQ ioctl fills the request structure's freq field by setting the exponent to 0 and the mantissa to the current channel number. The iwconfig tool works around this behaviour by looking up the frequency from the channel table if a frequency below 1kHz is returned, other tools (e.g. kwlaninfo) don't. According to the comment in the iwconfig source the driver is supposed to return the frequency, not the channel number. Signed-off-by: Ingo van Lil Signed-off-by: Zhu Yi Signed-off-by: John W.
