Hi, We are trying to develop an algorithm by using the information of RTS reception at the receiver side. (actually, we need the preceding frame of A-MPDU). As far as we know, RTS/CTS exchange is done by firmware of NIC. However, in monitor mode, we quite sure that the RTS/CTS frame reception should be reported to upper layer. As an evidence, Wireshark can capture and display the RTS/CTS reception. However, mac80211 and device driver (e.g., ath10k) can not recognize the reception of RTS even if we put the WiFi NIC in monitor mode. We check the type and subtype of frame_control field for all the received frames at the “ieee80211_rx_monitor” function of mac80211. We can find the reception of data frames amd mgmt frames, but there is no RTS/CTS frame. (We confirm that there is the RTS/CTS frame by using wireshark.) Is there any way to know the information about RTS reception in mac80211 or device driver? Thank you. -- Okhwan Lee, -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
