Latest CVS snapshot from might help a bit with INFDROP events (assuming they are generated due to CommTallies).

It is the firmware delaying the sending of multicast/broadcast frames. I do not configure this at all, but if they are indeed delayed, it might default to such behavior. However, I do not know whether it would be possible to change this somehow. Currently the only thing somewhat related to this is TIM setting, but other than that, there is no information about PS station given to firmware (unless it snoops info from data frame headers).
