Provide 2 files on the debugfs:
- "rxon": write channel (1..4) to open Rx on it, 0 to rxoff
- "tx_mgmt": write binary frame, starting from MAC header
one need to care about turning receiver on/off before/after tx_mgmt
Correct sequence is:
echo $channel > rxon
cat mfmt_frame > tx_mgmt
echo 0 > rxon

If scan has not finished in some reasonable time (10sec), interpret it as
if firmware error occurs but was not reported. Firmware should report
scan completion for every scan request, so it is error condition indeed.

When disconnecting some CID, corresponded Tx vring get released. During vring
release, all descriptors get freed. It is possible that Tx NAPI working on the same
vring simultaneously. If it happens, descriptor may be double freed.
To protect from the race above, make sure NAPI won't process the same vring.
Introduce 'enabled' flag in the struct vring_tx_data. Proceed with Tx NAPI only if
'enabled' flag set. Prior to Tx vring release, clear this flag and make sure NAPI
get synchronized.
NAPI enablement status protected by wil->mutex, add protection where it was
missing and check for it.
During reset, disconnect all peers first, then proceed with the Rx vring. It allows for
the disconnect flow to observe proper 'wil->status' and correctly notify cfg80211 about
connection status change

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.
