Hi All, I want to write implement PCF in mac80211 below Atheros ath9k Driver which has no PCF support now. So I must periodic send CF-Poll + [DATA] after sending a Beacon and set up the response for PCF in STA. I think I should know, 1. How to setup a timer to count for this PCF period and CF-Poll period. How to deal with that timer interrupt. 2. How to create a poll table to poll those associated STAs. Can you give me some examples or point out which part I should learn so that I can implement those PCF mechanism in mac80211?
