* Disable the reorder release timer for now.
*
* The current implementation lacks a proper locking scheme
* which would protect vital statistic and debug counters
* from being updated by two different but concurrent BHs.
*
* More information about the topic is available from:
* - thread: http://marc.info/?t=128635927000001
*
* What was wrong:
* => http://marc.info/?l=linux-wireless&m=128636170811964
* "Basically the thing is that until your patch, the data
* in the struct didn't actually need locking because it
* was accessed by the RX path only which is not concurrent."
*
* List of what needs to be fixed:
* => http://marc.info/?l=linux-wireless&m=128656352920957
