rtl8xxxu_bss_info_changed()
priv->vif gets already set in rtl8xxxu_add_interface, there is no need
to set it also in rtl8xxxu_bss_info_changed().

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.

To prepare for concurrent mode, enhance rtl8xxxu_set_mac() to write the
mac address of the respective interface to REG_MACID or REG_MACID1.
Remove the call to rtl8xxxu_set_mac() from the init function as we set
it in rtl8xxxu_add_interface() later anyway.
Until rtl8xxxu_add_interface() can handle both interfaces, call
rtl8xxxu_set_mac() with port_num = 0.

Subject: [PATCH 09/21] wifi: rtl8xxxu: support setting bssid register for
multiple interfaces
To prepare for concurrent mode, enhance rtl8xxxu_set_bssid() to write the
BSSID of the respective interface to REG_BSSID or REG_BSSID1.
Like done with rtl8xxxu_set_mac(), call rtl8xxxu_set_bssid() with
port_num = 0, until the callers also support multiple interfaces.

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.

As we only want to support AP mode/sending beacons on port 0, only change

Call set_linktype() and set_mac() with the appropriate port_num.

Subject: [PATCH 17/21] wifi: rtl8xxxu: add macids for STA mode
Until now, the driver only assigned a dedicated macid for connections
made in AP mode, in STA mode the return value of rtl8xxxu_get_macid()
was simply 0.
To differentiate between port 0 and 1, when both are in STA mode,
allocate a second macid (with value 1) and set sta_info->macid according
to the used port_num in rtl8xxxu_sta_add().

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 21/21] wifi: rtl8xxxu: declare concurrent mode support for
8188f
Everything is in place now for concurrent mode, we can tell the system
that we support it.
We will allow a maximum of 2 virtual interfaces, one of them can be in
AP mode.

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.

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.

From 94dd7ce1885e530a7b10bbe50d5d68ba1bb99e6e Mon Sep 17 00:00:00 2001

Date: Mon, 5 Feb 2024 10:30:40 +0100
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.

Subject: [PATCH] wifi: rtl8xxxu: check vif before using in rtl8xxxu_tx()
The 'vif' is from tx_info of SKB, and other codes check 'vif' before using,
which raises smatch warnings:
drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c:5656 rtl8xxxu_tx()
warn: variable dereferenced before check 'vif' (see line 5553)
Compile tested only.
