Title:
RTL8723DE firmware bug: rtw_pci 0000:0d:00.0: failed to send h2c
command

Status in linux package in Ubuntu:
Expired

Bug description:
WiFi (WLAN) Module: Realtek RTL8723DE (came with my HP laptop). Ubuntu
20.04 is the first Ubuntu release to have the module working out of
the box.

Network devices as output by 'inxi -N'
Device-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet driver: r8169
Device-2: Realtek RTL8723DE 802.11b/g/n PCIe Adapter driver: rtw_pci
Device-3: Realtek 802.11n WLAN Adapter type: USB driver: btusb

The error 'rtw_pci 0000:0d:00.0: failed to send h2c command' is logged
every time I use the module for internet access. The error is logged
more frequently especially if I stream a video and other related
tasks. The driver is stable but it may fail become unavailable unless
a cold boot is performed. The attached log contains the error logged
many times when I was streaming a video Today. According to
https://askubuntu.com/questions/1217892/system-responds-with-failed-
to-send-h2c-command-on-shutdown-what-does-that-me the error may be due
to a firmware issue or the driver issue. The error does not occur if
using the Realtek drivers obtained from Github in this link:
https://github.com/lwfinger/rtw88 and the driver of the module is
identified as rtw_8723de.
