An example of usage: iw dev wlanx vendor send 0x1374 0xad cfr-en bw method periodicity addr 0x1374: vendor id 0xad: : vendor subcmd id val: 0 to disable CFR capture 1 to enable CFR capture bw: CFR capture bandwidth(use the values in enum nl80211_chan_width) 1 - 20MHZ 2 - 40MHZ 3 - 80MHZ method: Method used by hardware to collect the CFR dump 0 - from the ACKs of QOS NULL packets 1 - from the ACKs of QOS NULL packets with phase 2 - from the ACK of probe response packet periodicity: Periodicity in ms at which CFR dump need to be collect 0 - single shot capture non zero - for Periodic captures mac_addr: mac address of the peer for which CFR capture is requested.
