Subject: iwl3945 losing association after resume from suspend

I am running 2.6.29.3. After resume from STR (assuming that long enough
time has passed) connectivity is lost. There is no messages in log. Just
running "wpa_cli reassociate" "fixes" it.

Is there any way driver can declare existing connection as "stale" and
tell wpa_supplicant to reassociate?

Thank you!

Send a disassociate event on resume if a few seconds have passed. But
in reality, this is usually done in userspace via pm-utils
suspend/resume scripts or some other mechanism based on the kernel's
uevents. It's not something that kernel drivers report back to
userspace, because that suspend/resume event is handled by the kernel in
a non-driver-specific fashion. You could use pm-utils scripts to
trigger the reassociation if you like, which is where most of the
userspace suspend/resume handling stuff lives these days.
