[PATCH] ipw2200: batch non-user-requested scan result notifications
ipw2200 makes extensive use of background scanning when unassociated or down. Unfortunately, the firmware sends scan completed events many times per second, which the driver pushes directly up to userspace. This needlessly wakes up processes listening for wireless events many times per second. Batch together scan completed events for non-user-requested scans and send them up to userspace every 4 seconds. Scan completed events resulting from an SIOCSIWSCAN call are pushed up without delay.
