iwlwifi: mvm: improve latency when there is a reorder timeout
When there is a reorder timeout, we may get to a situation where we have the timeout latency for all the next 64 frames. This happens since NSSN is behind for a while, and the driver won't release the frames, since it is not allowed by NSSN. As a result the frame is stored in the reorder buffer although there is no hole, and released 100 ms later. Add a direct comparison to the reorder buffer head, and release immediately if possible. For example: Frame 0 is missed. We receive frame 1, and store it in the buffer. After 100 ms, frame 1 is released and reorder buffer head is 2. We then receive frame 2, with NSSN 0, and store it instead of releasing it. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
