wireless: add new wil6210 802.11ad 60GHz driver
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.
