From e815de422c1dc2fe787c6f3edba81f3cf0176e32 Mon Sep 17 00:00:00 2001 From: Zhu Yi Date: Thu, 2 Mar 2006 05:55:51 +0800 Subject: [PATCH] [PATCH] ipw2200: Filter unsupported channels out in ad-hoc mode Currently iwlist ethX freq[uency]/channel lists all the channels the card supported for the current region, which includes some channels can only be used in infrastructure mode. This patch filters these channels out if the card is currently in ad-hoc mode. Signed-off-by: Zhu Yi Signed-off-by: John W.
