Enabling packet aggregation

[Olivier Marce]

Hi everybody
thanks a lot to all contributor for the development of this amazing soft 
that is hostapd.

I'm trying to use it in 11n with packet aggregation.
I put in my config file :
ieee80211n=1
wmm_enabled=1

So far I'm unable to see packets aggregation and BA in the AP and STA 
exchange. For testing I simply send a file over udp from one node to the 
other.

Did I miss some other configuration that enable packet aggregation ?
And/or does the aggregation triggered on particular conditions ?

Thanks for any hints

Regards
