This adds support for the 60 GHz 802.11ad Wilocity card through a new driver, wil6210. Wilocity implemented the firmware, QCA maintains the device driver. Currently supported: - STA: with security - AP: limited to 1 connected STA, security disabled - Monitor: due to a hardware/firmware limitation either control or non-control frames are monitored Using a STA and AP with this drive, one can assemble a fully functional BSS. Throughput of 1.2Gbps is achieved with iperf. The wil6210 cards have on-board flash memory for the firmware, the cards comes pre-flashed and no firmware download is required.
