Hi,
rt2x00reg.h defines the following sync modes:
63 enum tsf_sync {
64 TSF_SYNC_NONE = 0,
65 TSF_SYNC_INFRA = 1,
66 TSF_SYNC_BEACON = 2,
67 };
The sync value is on all ralink devices a two bit field.
On rt2800 however there is one more sync mode:
3: ap mode -> sync with nobody
At the moment we just programm TSF_SYNC_BEACON = 2 to the hardware which is
used for AdHoc beaconing setup (witch includes syncing the TSF with the TSF
of other AdHoc nodes). Basically the beaconing works correct but I _guess_
(and this is really just a guess) it would be possible to change the APs TSF
counter by sending a beacon with the same SSID to it.
So, do the older ralink devices really use only values 0..2 for the
synchronization setup?
Thanks,
Helmut
