Hi Oleksij, Adrian Thanks for Reply.
We are using Sony-UWA BR100 Adapter with AR7010+AR9280 chipset. We are using compat-wireless-3.6.8 in x86 machine with Intel Core i5. In monitor mode, we see for some packets the TSF difference is negative for consecutive captured packets, which confuses our analysis software in application. Last year Nov, Adrian had given a test-release with a fix for this issue, I was wondering whether this fix is updated in latest ath9k_htc firmware or not.
