Due to different RX/TX tasklet processing fix is different for those.
For RX we have to assure rx_tasklet do fail to resubmit buffers

rtw88: new Realtek 802.11ac driver
This is a new mac80211 driver for Realtek 802.11ac wireless network chips.
rtw88 now supports RTL8822BE/RTL8822CE now, with basic station mode
functionalities. The firmware for both can be found at linux-firmware.
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
For RTL8822BE: rtw88/rtw8822b_fw.bin
For RTL8822CE: rtw88/rtw8822c_fw.bin
And for now, only PCI buses (RTL8xxxE) are supported. We will add support
for USB and SDIO in the future. The bus interface abstraction can be seen
in this driver such as hci.h. Most of the hardware setting are the same
except for some TRX path or probing setup should be separated.
Supported:
* Basic STA/AP/ADHOC mode, and TDLS (STA is well tested)
Missing feature:
* WOW/PNO
* USB & SDIO bus (such as RTL8xxxU/RTL8xxxS)
* BT coexistence (8822B/8822C are combo ICs)
* Multiple interfaces (for now single STA is better supported)
* Dynamic hardware calibrations (to improve/stabilize performance)
Potential problems:
* static calibration spends too much time, and it is painful for
driver to leave IDLE state. And slows down associate process.
But reload function are under development, will be added soon!
* TRX statictics misleading, as we are not reporting status correctly,
or say, not reporting for "every" packet.
The next patch set should have BT coexistence code since RTL8822B/C are
combo ICs, and the driver for BT can be found after Linux Kernel v4.20.
So it is better to add it first to make WiFi + BT work concurrently.
Although now rtw88 is simple but we are developing more features for it.
Even we want to add support for more chips such as RTL8821C/RTL8814B.
Finally, rtw88 has many authors, listed alphabetically:

applied this broken (failed to compile) patch due to a bug in my patchwork
script.

brcmfmac: send mailbox interrupt twice for specific hardware device
For PCIE wireless device with core revision less than 14, device may miss
PCIE to System Backplane Interrupt via PCIEtoSBMailbox. So add sending
mail box interrupt twice as a hardware workaround.

brcmfmac: Add DMI nvram filename quirk for ACEPC T8 and T11 mini PCs
The ACEPC T8 and T11 mini PCs contain quite generic names in the sys_vendor
and product_name DMI strings, without this patch brcmfmac will try to load:
"brcmfmac43455-sdio.Default string-Default string.txt" as nvram file which
is way too generic.
The DMI strings on which we are matching are somewhat generic too, but
"To be filled by O.E.M." is less common then "Default string" and the
system-sku and bios-version strings are pretty unique. Beside the DMI
strings we also check the wifi-module chip-id and revision. I'm confident
that the combination of all this is unique.
Both the T8 and T11 use the same wifi-module, this commit adds DMI
quirks for both mini PCs pointing to brcmfmac43455-sdio.acepc-t8.txt .

p54: drop device reference count if fails to enable device
The function p54p_probe takes an extra reference count of the PCI
device. However, the extra reference count is not dropped when it fails
to enable the PCI device. This patch fixes the bug.

rtlwifi: rtl8723ae: Fix missing break in switch statement
Add missing break statement in order to prevent the code from falling
through to case 0x1025, and erroneously setting rtlhal->oem_id to
RT_CID_819X_ACER when rtlefuse->eeprom_svid is equal to 0x10EC and
none of the cases in switch (rtlefuse->eeprom_smid) match.
This bug was found thanks to the ongoing efforts to enable
-Wimplicit-fallthrough.
