[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 <yi.zhu@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
