	Thanks Thomas for your answer, 

	In ath9k_hw_beaconinit() the mesh mode use the hadhoc beacon mode. I
try to change it, and  ath9k_set_beacon in
driver/net/Wireless/ath/ath9k/beacon.c, but after these modifications, no
beacon are sent (I think my change are wrong).

	Could you give me the old patch, I can try to update it with the
latest compat, and I will send to you an updated patch. 

	Thanks for your help.

This is because ath9k currently uses the hardware's adhoc beaconing mode for
mesh. See ath9k_hw_beaconinit() in drivers/net/wireless/ath/ath9k/hw.c. This
is probably wrong, and we have a patch to beacon with AP mode, but I'll have
to dig it up.
