[ath9k-devel] MCS Information Corrupted in Sniffed A-MPDU Packets

2015-12-14 Thread Jinghao Shi
Hi, Recently I used an OpenWRT router (TP-LINK WDR3500, AR9340, ATH9K) to sniff packets, and I found that the MCS information in the radiotap header is possible corrupted. In theory, all A-MPDU subframes should be sent in the same bit rate (MCS/BW/GI), since they have the same PPDU header. Howeve
