hi, I am using ath9k device drriver. I wanted to get FCS value in userspace. It looks like radiotap header doesn't give it. How can I get it ?
Also there are certain variables that kernel has: like crc err, phy err which I want in the userspace. How can I get them per packet ? I know cat /sys/kernel/debug/ieee80211/phy0/ath9k/recv gives me the above values but I don't get if I do a subsequent cat on this file, I will get the sum of new errors+ old errors or the count of errors after the last cat on /sys... ? How do I know these values were reset after an overflow of their datatype ? Is there a better way to get these values ? For now, I can just interpret them as some values on phyX interface (which is not very useful) Abhinav
