This series adds support for the 802.11ac data-rates available on the WCN3680. WCN3680: - Has one spatial stream - MCS9 80Mhz 400ns guard interval - 433.3 Mbps - RX STBC - LDPC (host dependant) - MU-MIMO (host dependant) - Tx beamformee (host dependant) Declared data-rates are around 200 Mbps https://preview.tinyurl.com/y2w3jb2b iw wlan0 link Connected to 04:d4:c4:3a:fd:f4 (on wlan0) SSID: linaro-test_5G freq: 5300 RX: 761467 bytes (4302 packets) TX: 2492 bytes (28 packets) signal: -29 dBm rx bitrate: 433.3 MBit/s VHT-MCS 9 80MHz short GI VHT-NSS 1 tx bitrate: 6.0 MBit/s bss flags: short-slot-time dtim period: 3 beacon int: 100 Test Hardware: 20MHz channels [ ID] Interval Bitrate [ 5] 0.00-60.00 sec 51.6 Mbits/sec [ 5] 0.00-60.16 sec 51.4 Mbits/sec 40MHz channels [ 5] 0.00-60.00 sec 109 Mbits/sec [ 5] 0.00-60.15 sec 109 Mbits/sec 80MHz channels [ 5] 0.00-60.00 sec 141 Mbits/sec [ 5] 0.00-60.01 sec 141 Mbits/sec db410c: [ ID] Interval Bitrate [ 5] 0.00-60.00 sec 47.9 Mbits/sec [ 5] 0.00-60.02 sec 47.7 Mbits/sec Sony M4 Aqua - believed to contain a 3680 with 3.10 downstream prima: 20MHz channels [ ID] Interval Bitrate [ 5] 0.00-60.00 sec 25.5 Mbits/sec [ 5] 0.00-60.16 sec 25.5 Mbits/sec 40MHz channels [ 5] 0.00-60.00 sec 50 Mbits/sec [ 5] 0.00-60.15 sec 50 Mbits/sec 80MHz channels [ 5] 0.00-60.00 sec 67.8 Mbits/sec [ 5] 0.00-60.01 sec 67.8 Mbits/sec The wcn3680 uses the same parameter passing mechanism as earlier versions 3620 and 3660 however it also supports extended VHT parameters for STA and BSS setup. I've taken the downstream firmware config almost as-is in terms of parameters send over the SMD bus to the target with the caveat of switching off power-save offload. I do have some housekeeping patches in the middle of this series where I functionally decompose some of the existing code, which in my opinion needed some attention before adding any more code to it. Lastly, I've tested on wcn3680 and wcn3620, since the extended VHT parameters only apply to wcn3680 the code-paths for wcn3620 should be the same for wcn3660.
