I'm pinging the access point from an associated wifi client: when this 
message appears one or two pings are lost. Previously, when such 
messages didn't appear, no pings were lost. Maybe the reply timeouts and 
is not completely lost, I'll do more tests asap.

Actually the timing is highly variable, it may happen once a second, 
like once every 15 seconds or more. Usually (in the two hours I tried) 
every 2-5 seconds.

hw.ath.shortcal = 0, right?

I'll try, I haven't done additional tests before knowing what would be 
useful for debugging.
