If you tried changed shortRetryLimit or longRetryLimit RIDs (FD48,
FD49), it was doomed to fail.. Those are read only just like all other
FD?? RIDs. However, you can set cnfAltRetryCount (FC32) and indeed, Host
AP driver already supports this so that you can use 'iwconfig wlan0
retry <val>' to configure retry limits. Each TX frame can then be sent
with the fixed long/short retry limit or with the configurable
alternative retry limit.
