Subject: [PATCH] d80211: Take lowlevel driver's channel change time into account during scanning.
Date: Sat, 01 Jul 2006 22:40:38 +0200 [thread overview]
Message-ID: <44A6DDC6.1040005@kpnplanet.nl> (raw)
Make the dscape stack take the driver-supplied channel change time into
account when actively scanning for networks.
This particularly has been a problem in the rt2x00 driver, where
configuration changes are done via a work-queue, and
the subsequent channel changes failed due to the dscape stack scheduling
a channel update while the previous one had not
been performed yet, resulting in failed scans.
