I haven't tested your patches yet, but I'm a bit concerned about the timer. Timers usually create problems of their own and using them wrong affect power consumption. I don't have time to read the patches in detail, but can you give a short summary how the timer works? How often is it fired? What happens when the data path is idle? And is it absolutely necessary to use a timer? Can't we use tx completions or some other existing event from firmware to accomplish the same? -- Kalle Valo _______________________________________________ ath9k-devel mailing list ath9k-devel@lists.ath9k.org https://lists.ath9k.org/mailman/listinfo/ath9k-devel
