Hi,
here is another diff that should fix associating with
some APs that currently don't work.
If block ack is active and the first frame got lost,
subsequent packets are held back until a timeout expires.
When this timeout expires, the gap at the start of the
reorder buffer is skipped and subsequent frames that are
sitting in the reorder buffer can be processed.
In order to make this work, flush the reorder buffer
after skipping the sequence number gap. Without doing this,
packets in the reorder buffer will remain there until a new
block ack packet is received.
Found and fix provided by Christian Ehrhardt
ok?
