As we're running out of hardware capability flags pretty quickly,
convert them to use the regular test_bit() style unsigned long
bitmaps.
This introduces a number of helper functions/macros to set and to
test the bits, along with new debugfs code.
The occurrences of an explicit __clear_bit() are intentional, the
drivers were never supposed to change their supported bits on the
fly. We should investigate changing this to be a per-frame flag.

Currently, wcn36xx only asks for a TX BA session if it has
already established one for RX. Thus, two wcn36xx devices cannot
do a-mpdu between themselves since they both wait for the other
to go first. Fix this by starting a BA session after a few QoS
data frames have been sent to a STA.

Pull driver core update from Greg KH:
"Here's the set of driver core patches for 3.19-rc1.
They are dominated by the removal of the .owner field in platform
drivers. They touch a lot of files, but they are "simple" changes,
just removing a line in a structure.
Other than that, a few minor driver core and debugfs changes. There
are some ath9k patches coming in through this tree that have been
acked by the wireless maintainers as they relied on the debugfs
changes.
Everything has been in linux-next for a while"

Allow drivers to support NL80211_SCAN_FLAG_RANDOM_ADDR with software
based scanning and generate a random MAC address for them for every
scan request with the flag.

A platform_driver does not need to set an owner, it will be populated by the
driver core.

The dtim period sent to FW was 0 because the dtim period
was never set. This caused an incorrect dtim count to be sent in
beacons.

If wowlan if off mac80211 will stop / start the driver on suspend /
resume. This causes problems on resume since request_firmware is called
from start. Fix this by caching the nv.

This is a mac80211 driver for Qualcomm WCN3660/WCN3680 devices. So
far WCN3660/WCN3680 is available only on MSM platform.
Firmware can be found here:
https://www.codeaurora.org/cgit/external/hisense/platform/vendor/qcom-opensource/wlan/prima/tree/firmware_bin?h=8130_CS
Wiki page is available here:
