beacons and hostapd

Hello,
I have a question about beacons: something very strange happened to me.
I use the rt73usb driver

I had added printk messages in the beacon transmit method
ieee80211_beacon_get()
in net/mac80211/tx.c and also in the driver : it is
rt2x00queue_update_beacon() method, which in fact
calls ieee80211_beacon_get(). (net/wireless/rt2x00/rt2x00queue.c)

What is strange is that when I start hostapd and wait for more than 3
minutes, I see only 3 calls to
ieee80211_beacon_get() !

But hostapd in fact sends 10 beacons in a second by default - so why
don't I see messages of ieee80211_beacon_get() ?

And BTW, I added sniffing on a remote device and I indeed see that 10
beacons per second are sent!
And I am using the latest git hostapd source code from today.

rgs,
Mark
