Description

In an effort to reduce wifi driver burdens AR-1745, I went through the 6.10 kernel to check if any third party wifi drivers can be removed.

The following drivers are part of the mainline kernel as of 6.10:

• RTL8723CS (driver: RTW88)
• RTL8811CU and RTL8821C (driver: RTW88)
• RTL8192EU (driver: RTL8XXXU)

To give them some more time in the oven, use them not from 6.10 but from 6.11 onwards. I went through the Armbian forums, Atlassian and GiHub issues to see if anyone had used those drivers for these chips in the past and had reported issues. But I haven't found anything yet.

RTL8723DS is also supported by RTW88, but I have not touched that driver since it is still required for the RockPi-S wifi to work properly as reported by @brentr

Jira reference number AR-1745

How Has This Been Tested?

• [x] Build success: ./compile.sh BOARD=nanopc-cm3588-nas BRANCH=edge RELEASE=trixie EXPERT=yes KERNEL_CONFIGURE=no BUILD_MINIMAL=no BUILD_DESKTOP=no
• [ ] Mainline drivers should be tested

LOOKING FOR TESTERS:

Drivers for RTL8811CU, RTL8821C and RTL8192EU are available also in 6.9, so if you have a device with those chips, it would be very nice if you could test them with their respective kernel driver (RTW88 or RTL8XXXU). You may have to enable them in your board's kernel config.

If you have a board with a RTL8723DS chip, please test the RTW88 driver. If RockPi-S is the only board which broken RTL8723DS driver, we could switch most other boards to RTW88 for this chip.
