Hi, I have been browsing the driver code for some backoff related stuff. Specifically, I am looking for a way to count the number of backoffs on AR5212 based cards. I have seen a backoff count register for AR5210 but cannot find any such thing for AR5212.
Also, what is "Backoff persistence factor" and "Backoff threshold"? I understand what backoff is but I have no idea what persistence means here. Apparently, the driver does not make use of this register and trying to look for some more information in Sam's openhal didn't help. I would really appreciate if someone can provide me more information about these registers and whether it is possible to count the number of backoffs on AR5212 cards. #*define* AR5K_DCU_MISC_BACKOFF_PERSIST <http://wifi-dev:8080/source/s?refs=AR5K_DCU_MISC_BACKOFF_PERSIST&project=/wireless-testing> 0x00001000 /* Persistent backoff */ #*define* AR5K_DCU_MISC_BACKOFF <http://wifi-dev:8080/source/s?refs=AR5K_DCU_MISC_BACKOFF&project=/wireless-testing> 0x0000003f /* Mask for backoff threshold */ Thanks, -Qasim
