Helmut Schaa 14a4dfe2ff ipw2200: fix scanning while associated ... This patch fixes sporadic firmware restarts when scanning while associated. The firmware will quietly cancel a scan (while associated) if the dwell time for a channel to be scanned is larger than the time it may stay away from the operating channel (because of DTIM catching). Unfortunately the driver is not notified about the canceled scan and therefore the scan watchdog timeout will be hit and the driver causes a firmware restart which results in disassociation. This mainly happens on passive channels which use a dwell time of 120 whereas a typical beacon interval is around 100. The patch changes the dwell time for passive channels to be slightly smaller than the actual beacon interval to work around the firmware issue. Furthermore the number of allowed beacon misses is increased from one to three as otherwise most scans (while associated) won't complete successfully. However scanning while associated will still fail in corner cases such as a beacon intervals below 30. Signed-off-by: Helmut Schaa <helmut.schaa@googlemail.com> Signed-off-by: John W.
