Quantenna Pearl device exposes multiple (up to 3) radio interfaces under
single PCIe function. So far all the wiphy devices were attached to the
same pcie device. As a result, all different wireless network devices
were reported under the same sysfs directory for pcie device, e.g.:
$ ls /sys/class/net/wlan0/device/net/
wlan0 wlan1
It turns out that such behavior may confuse various users of wireless
subsystem. For instance, it turned out to be the case for:
- Linux init systems, e.g. for renaming based on parent device
- OpenWRT configuration scripts
Suggested solution is to add an intermediate virtual platform device
for each radio interface.

Enable WPA3 OWE support in AP mode. Driver currently supports cards that
offload OWE processing to userspace. This patch adds all the required
tools for such offloading. Firmware requests OWE processing sending new
UPDATE_OWE event to driver, which uses cfg80211_update_owe_info_event to
notify userspace software. After OWE processing is completed, userspace
sends calculated IEs to firmware using update_owe_info cfg80211 callback.

Now that there is support for BIGTK configuration and AP/STA
functionality for using BIP with Beacon frames, indicate support for the
Beacon protection functionality.
Johannes: move this to hwsim, since it's not clear that all drivers
using mac80211 will do this correctly - lots of them modify the
beacon before transmission e.g. to update the TIM element, and that
would obviously break the signature.

Overwriting the RMAC_CHFREQ register is not reliable enough, as the firmware
could potentially write it again.
Since there is no PHY index indication in the rx info, we need to use another
way:
If both PHYs are using different channels, find the PHY where chfreq matches
the register value.
The only corner case remaining is when both PHYs are using the same channel.
In that case, the per-packet noise value on the primary PHY will have
information belonging to the chains of the secondary PHY from the previous
received packet of that PHY. The secondary PHY will set noise to 0 for extra
chains.

Setting the tx power by manipulating EEPROM may in some cases not be enough,
since it only covers the base target power and not per-rate offsets.
In other cases, it could limit tx power of rates too much, possibly reducing
throughput or range.

different values of Nss.
