Hi,
?
I had implemented descriptor based TPC(per?packet TPC)?for ath9k by setting the various TxPower control fields within the Tx Descriptor (set11n_txdesc) for the Tx frames. From my testing, for some reason the Tx power values present in the descriptor are not applied by the hardware(I am using ar5416 based card). In contrast, if "iwconfig txpower" (in spite of the known bug) is used(forced to apply by down/up'ing the interface) the power change is noticed from the sniffer.
????? Is any additional setup(transmit queue, txdesc interrupt or hardware setup) needs to be done to force the hardware read and process the tx descriptors? Appreciate if any one could shed more light on it or share their own experience if they had tried to implement this feature.
?
Thanks,
Ramkumar.
