The problem is a bad degradation in throughput with our new 9000 family
of devices because when aggregation times out we stop the aggregation
internally in the firmware but don't send a delba.  Then on the AP side,
 also with our driver, we don't handle the timeout as we should, so
aggregations the devices get out of sync and BA sessions are not
possible anymore, limiting our throughput to ~30Mbps, in some specific
internal tests.

Okay, if you think the (one-liner) iwlwifi driver fix is -rc'able, I'll
resend this in a patchset including both changes.
