Error 19 is defined as CMD_STATUS_WRONG_NESTING from the wlcore firmware,
and seems to mean that the firmware no longer wants to see the quirk
handling for WLCORE_QUIRK_START_STA_FAILS done.
This quirk got added with commit 18eab430700d ("wlcore: workaround
start_sta problem in wl12xx fw"), and it seems that this already got fixed
in the firmware long time ago back in 2012 as wl18xx never had this quirk
in place to start with.
As we no longer even support firmware that early, to me it seems that it's
safe to just drop WLCORE_QUIRK_START_STA_FAILS to fix the error. Looks
like earlier firmware got disabled back in 2013 with commit 0e284c074ef9
("wl12xx: increase minimum singlerole firmware version required").
If it turns out we still need WLCORE_QUIRK_START_STA_FAILS with any
firmware that the driver works with, we can simply revert this patch and
add extra checks for firmware version used.
With this fix wlcore reconnects properly after a beacon loss.

mt7601u: check the status of device in calibration
When the usb device being plugged out, before ieee80211 gets to know the
hw being removed, it gets to know that the association status changed,
and thus ask for the device to do the calibration. This causes error as
the hw is absent.
This can be avoid by checking the status of the device before sending
the calibration request to the device.

mt7601u: process URBs in status EPROTO properly
When the usb device being plugged out, before the usb_driver:disconnect
called by e.g workqueue, it is possible that some URBs are still in
processing, and being marked as EPROTO in host controller.
Those URBs should not be scheduled in complete_rx callback function to
get further processing.

mwifiex: pcie: Drop bogus __refdata annotation
As the Marvell PCIE WiFi-Ex driver does not have any code or data
located in initmem, there is no need to annotate the mwifiex_pcie
structure with __refdata. Drop the annotation, to avoid suppressing
future section warnings.

rtw88: coex: set 4 slot TDMA for BT link and WL busy
To protect both of WL/BT performance while BT is under re-link state.
4-slot mode TDMA can make the re-link more sensitive and mitigate the WL
throughput drop.

rtw88: 8821c: apply CCK PD level which calculates from dynamic mechanism
Hal function must follow the value that calculates from dynamic mechanism.

rtw88: reduce the log level for failure of tx report
Sometimes driver does not get tx report from firmware because wifi
environment is too noisy to get ack from AP about a TX frame,
or firmware is too busy to report driver in a estimated time.
But the condition will not affect wifi function or throughput.
So we reduce the log level to rtw_debug instead of scary backtrace.
