Subject: [PATCH 02/21] wifi: rtl8xxxu: prepare supporting two virtual
interfaces
To prepare for concurrent mode, add an array ("vifs") to rtl8xxxu_priv
to keep track of both interfaces.
Keep the old priv->vif as long there are still users of it and let
priv->vifs[0] point to the same location.

Subject: [PATCH 10/21] wifi: rtl8xxxu: support multiple interfaces in
set_aifs()
In concurrent mode supported by this driver, both interfaces will use
the same channel and same wireless mode.
It is therefore possible to get the wireless mode by checking the first
connected interface.

Add a custom struct to store in vif->drv_priv with a reference to
port_num and fill it when a new interface is added. Choose a free
port_num for the newly added interface.
As we only want to support AP mode/sending beacons on port 0, only change
the beacon settings if a new interface is actually assigned to port 0.
Call set_linktype() and set_mac() with the appropriate port_num.

Explicit changes to BEACON will only happen for AP type interfaces, so

Subject: [PATCH 19/21] wifi: rtl8xxxu: add hw crypto support for AP mode
Add a custom function for allocating entries in the sec cam. This allows
us to store multiple keys with the same keyidx.
The maximum number of sec cam entries for 8188f is 16 according to the
vendor driver. Add the number to rtl8xxxu_fileops, so that other chips
which might support more entries, can set a different number there.
Set the bssid as mac address for group keys instead of just using the
ethernet broadcast address and use BIT(6) in the sec cam ctrl entry
for differentiating them from pairwise keys like in the vendor driver.
Add the TXDESC_EN_DESC_ID bit and the hw_key_idx to tx
broadcast/multicast packets in AP mode.
Finally, allow the usage of rtl8xxxu_set_key() for AP mode.

Subject: [PATCH 20/21] wifi: rtl8xxxu: make supporting AP mode only on port 0
transparent
When the driver is used for concurrent mode, both virtual interfaces can
be set to station or AP mode, though only one can be in AP mode at the
same time.
In order to keep the code simple, use only hw port 0 for AP mode. When
an interface is added in AP mode which would be assigned to port 1, use
a switch_port function to transparently swap the mapping between virtual
interface and hw port.

Subject: [PATCH 1/2] wifi: rtl8xxxu: Fix LED control code of RTL8192FU
Some devices, like the Comfast CF-826F, use LED1, which already works.
Others, like Asus USB-N13 C1, use LED0, which doesn't work correctly.
Write the right values to the LED control registers to make LED0 work
as well.
This is unfortunately tested only with the Comfast CF-826F.

Subject: [PATCH 2/2] wifi: rtl8xxxu: Fix off by one initial RTS rate
rtl8xxxu_set_basic_rates() sets the wrong initial RTS rate. It sets the
next higher rate than the one it should set, e.g. 36M instead of 24M.
The while loop was supposed to find the index of the most significant
bit which is 1, but it was copied incorrectly from the vendor driver.
Use __fls() instead.

Subject: [PATCH] wifi: rtl8xxxu: add missing number of sec cam entries for all
variants
Commit b837f78fbffa ("wifi: rtl8xxxu: add hw crypto support for AP
mode") introduced max_sec_cam_num as a member of rtl8xxxu_fileops.
It was missed to set this number for all variants except 8188f, which
caused rtl8xxxu_get_free_sec_cam() to always return 0 and therefore breaking
encrypted traffic.
Fix it by adding the numbers for all variants. The values are taken from
the vendor drivers and rtlwifi.

Subject: [PATCH] wifi: rtl8xxxu: fix error messages
The first parameter of WARN_ONCE() is a condition so this code will end
up printing the function name instead of the proper message.

Subject: [PATCH] wifi: rtl8xxxu: update rate mask per sta
Until now, rtl8xxxu_watchdog_callback() only fetches RSSI and updates
the rate mask in station mode. This means, in AP mode only the default
rate mask is used.
In order to have the rate mask reflect the actual connection quality,
extend rtl8xxxu_watchdog_callback() to iterate over every sta. Like in
the rtw88 driver, add a function to collect all currently present stas
and then iterate over a list of copies to ensure no RCU lock problems
for register access via USB. Remove the existing RCU lock in
rtl8xxxu_refresh_rate_mask().
Since the currently used ieee80211_ave_rssi() is only for 'vif', add
driver-level tracking of RSSI per sta.
