Hello, As I was working with ath10k drivers, I have discovered that only CT firmware/driver combination is able to report tx_info to mac80211 layer. I've built latest LEDE image for my hardware (Netgear Nighthawk X4S R7800) with both ath10k-ct driver from Ben and CT firmware. This combination of software provides the data I need, however, the throughput is severely limited :/
All tests are performed between two of these devices in mesh mode with no encryption. Here are some of the iperf results: NODE 1 (QCA) ----- NODE 2 (CT) Iperf server on NODE 2 Connecting to host 192.168.1.2, port 5201 [ 4] local 192.168.1.1 port 41058 connected to 192.168.1.2 port 5201 [ ID] Interval Transfer Bandwidth Retr Cwnd [ 4] 0.00-1.00 sec 5.97 MBytes 50.0 Mbits/sec 0 242 KBytes [ 4] 1.00-2.00 sec 6.75 MBytes 56.6 Mbits/sec 0 454 KBytes [ 4] 2.00-3.00 sec 7.03 MBytes 58.9 Mbits/sec 0 734 KBytes [ 4] 3.00-4.00 sec 6.60 MBytes 55.4 Mbits/sec 0 973 KBytes [ 4] 4.00-5.00 sec 6.83 MBytes 57.3 Mbits/sec 0 1.13 MBytes [ 4] 5.00-6.00 sec 6.36 MBytes 53.3 Mbits/sec 0 1.39 MBytes [ 4] 6.00-7.00 sec 6.73 MBytes 56.6 Mbits/sec 0 1.65 MBytes [ 4] 7.00-8.00 sec 6.54 MBytes 54.9 Mbits/sec 0 1.76 MBytes [ 4] 8.00-9.00 sec 6.50 MBytes 54.4 Mbits/sec 0 1.76 MBytes [ 4] 9.00-10.00 sec 6.74 MBytes 56.5 Mbits/sec 0 1.76 MBytes - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bandwidth Retr [ 4] 0.00-10.00 sec 66.0 MBytes 55.4 Mbits/sec 0 sender [ 4] 0.00-10.00 sec 65.3 MBytes 54.8 Mbits/sec receiver ---------------------------------------------------------------------------- NODE 1 (QCA) ----- NODE 2 (QCA) Iperf server on NODE 2 Connecting to host 192.168.1.2, port 5201 [ 4] local 192.168.1.1 port 58770 connected to 192.168.1.2 port 5201 [ ID] Interval Transfer Bandwidth Retr Cwnd [ 4] 0.00-1.00 sec 22.9 MBytes 191 Mbits/sec 0 157 KBytes [ 4] 1.00-2.02 sec 26.3 MBytes 217 Mbits/sec 0 296 KBytes [ 4] 2.02-3.05 sec 30.7 MBytes 251 Mbits/sec 0 622 KBytes [ 4] 3.05-4.02 sec 30.0 MBytes 260 Mbits/sec 0 930 KBytes [ 4] 4.02-5.02 sec 33.9 MBytes 283 Mbits/sec 0 930 KBytes [ 4] 5.02-6.04 sec 32.5 MBytes 269 Mbits/sec 0 1.00 MBytes [ 4] 6.04-7.02 sec 36.2 MBytes 310 Mbits/sec 0 1.11 MBytes [ 4] 7.02-8.06 sec 38.6 MBytes 312 Mbits/sec 0 1.28 MBytes [ 4] 8.06-9.01 sec 34.9 MBytes 307 Mbits/sec 0 1.42 MBytes [ 4] 9.01-10.04 sec 37.3 MBytes 304 Mbits/sec 0 1.49 MBytes - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bandwidth Retr [ 4] 0.00-10.04 sec 323 MBytes 270 Mbits/sec 0 sender [ 4] 0.00-10.04 sec 322 MBytes 269 Mbits/sec receiver ----------------------------------------------------------------------------- NODE 1 (CT) ----- NODE 2 (QCA) Iperf server on NODE 2 Connecting to host 192.168.1.2, port 5201 [ 4] local 192.168.1.1 port 36820 connected to 192.168.1.2 port 5201 [ ID] Interval Transfer Bandwidth Retr Cwnd [ 4] 0.00-1.00 sec 2.09 MBytes 17.5 Mbits/sec 0 22.6 KBytes [ 4] 1.00-2.00 sec 1.16 MBytes 9.71 Mbits/sec 0 22.6 KBytes [ 4] 2.00-3.00 sec 1.12 MBytes 9.43 Mbits/sec 0 22.6 KBytes [ 4] 3.00-4.00 sec 1.13 MBytes 9.45 Mbits/sec 0 22.6 KBytes [ 4] 4.00-5.00 sec 1.12 MBytes 9.38 Mbits/sec 0 22.6 KBytes [ 4] 5.00-6.00 sec 1.12 MBytes 9.36 Mbits/sec 0 22.6 KBytes [ 4] 6.00-7.00 sec 1.16 MBytes 9.73 Mbits/sec 0 22.6 KBytes [ 4] 7.00-8.00 sec 1.16 MBytes 9.71 Mbits/sec 0 22.6 KBytes [ 4] 8.00-9.00 sec 1.13 MBytes 9.48 Mbits/sec 0 22.6 KBytes [ 4] 9.00-10.00 sec 1.12 MBytes 9.41 Mbits/sec 0 22.6 KBytes - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bandwidth Retr [ 4] 0.00-10.00 sec 12.3 MBytes 10.3 Mbits/sec 0 sender [ 4] 0.00-10.00 sec 12.3 MBytes 10.3 Mbits/sec receiver ----------------------------------------------------------------------------- NODE 1 (CT) ----- NODE 2 (CT) Iperf server on NODE 2 *Unable to establish peering until I add monitor mode devices on both sides.* Connecting to host 192.168.1.2, port 5201 [ 4] local 192.168.1.1 port 41328 connected to 192.168.1.2 port 5201 [ ID] Interval Transfer Bandwidth Retr Cwnd [ 4] 0.00-1.00 sec 1.51 MBytes 12.7 Mbits/sec 0 31.1 KBytes [ 4] 1.00-2.00 sec 1.47 MBytes 12.4 Mbits/sec 0 31.1 KBytes [ 4] 2.00-3.00 sec 1.46 MBytes 12.2 Mbits/sec 0 31.1 KBytes [ 4] 3.00-4.00 sec 1.49 MBytes 12.5 Mbits/sec 0 31.1 KBytes [ 4] 4.00-5.00 sec 1.55 MBytes 13.0 Mbits/sec 0 31.1 KBytes [ 4] 5.00-6.00 sec 1.49 MBytes 12.5 Mbits/sec 0 31.1 KBytes [ 4] 6.00-7.00 sec 1.59 MBytes 13.3 Mbits/sec 0 31.1 KBytes [ 4] 7.00-8.00 sec 1.36 MBytes 11.4 Mbits/sec 0 31.1 KBytes [ 4] 8.00-9.00 sec 1.77 MBytes 14.9 Mbits/sec 0 48.1 KBytes [ 4] 9.00-10.00 sec 2.92 MBytes 24.5 Mbits/sec 0 48.1 KBytes - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bandwidth Retr [ 4] 0.00-10.00 sec 16.6 MBytes 13.9 Mbits/sec 0 sender [ 4] 0.00-10.00 sec 16.5 MBytes 13.9 Mbits/sec receiver Another strange thing I noticed was inability to mesh two devices running CT firmware until I created monitor mode devices - this leads me to believe that there's some kind of filtering bug. I've tried several different CT firmware versions - http://www.candelatech.com/downloads/ath10k-9984-10-4/ath10k-fw-beta/firmware-5-ct-full-community.bin http://www.candelatech.com/downloads/ath10k-9984-10-4/firmware-5-ct-full-community-7.bin-lede.001 http://www.candelatech.com/downloads/ath10k-9984-10-4/firmware-5-ct-full-community-7.bin-lede.004 - all of them behave in similar ways. P.S. Both devices are running in VHT80 mode on channel 36 and generally report very good connection (-30dBm-ish). _______________________________________________ ath10k mailing list [email protected] http://lists.infradead.org/mailman/listinfo/ath10k
