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.
