This warning is emitted because in the connect path, when trying to parse
target BSS parameters, we dereference a RCU pointer whithout being in RCU
critical section.
Fix RCU dereference usage by moving it to a RCU read critical section. To
avoid wrapping the whole wilc_parse_join_bss_param under the critical
section, just use the critical section to copy ies data

bcm4331 seems to not function correctly with QoS support. This may be due
to issues with currently available firmware or potentially a device
specific issue.
When queues that are not of the default "best effort" priority are
selected, traffic appears to not transmit out of the hardware while no
errors are returned. This behavior is present among all the other priority
queues: video, voice, and background. While this can be worked around by
setting a kernel parameter, the default behavior is problematic for most
users and may be difficult to debug. This patch offers a working out-of-box
experience for bcm4331 users.
Log of the issue (using ssh low-priority traffic as an example):

rtl8xxxu_set_basic_rates() sets the wrong initial RTS rate. It sets the

The while loop was supposed to find the index of the most significant

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.

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.
