** Description changed:
+ [SRU Justification]
+
+ [Impact]
+
+ WCN685x hw2.1 takes additional/updated firmware for both WiFi and
+ Bluetooth function.
+
ath11k_pci 0000:71:00.0: BAR 0: assigned [mem 0xa6000000-0xa61fffff 64bit]
ath11k_pci 0000:71:00.0: enabling device (0000 -> 0002)
ath11k_pci 0000:71:00.0: Unsupported WCN6855 SOC hardware version: 18 17
ath11k_pci: probe of 0000:71:00.0 failed with error -95
+
+ [Fix]
+
+ WCN685x hw2.1 currently shares most WiFi firmware with hw2.0 except
+ for the directory path and a board-2.bin.
+
+ For Bluetooth, updated revision of qca/nvm_usb_00130201_gf* from
+ mainline are neccessary for Focal. Jammy has all of them already.
+
+ For kernel, many of the prerequisite works have been committed for
+ hw2.0 in bug 1945154, 1952215 and 1958850. Currently, while WiFi 6G
+ will be turned off for the lack of userspace support, the only fix
+ necessary is to correct read mask of version info register.
+
+ [Test Case]
+
+ WiFi and Bluetooth devices should be up and running, pass basic
+ operations.

0000:71:00.0 Network controller [0280]: Qualcomm Device [17cb:1103] (rev 01)

Kernel driver in use: ath11k_pci
Kernel modules: ath11k_pci

+
+ [Where problems could occur]
+
+ At the time being, WCN685x WiFi 6G support will be turnef off
+ deliberately due to the lack of full support in the userspace
+ management tools.
+
+ [Other Info]
+
+ While this is a new hardware model from OEM program, it's only
+ nominated for Focal oem-5.14 kernel and the coming LTS Jammy.
