(Info) Progress Log
Progress Log:
- Done - modify Makefile to stop some unnecessary warnings.
- Tested - original code supports kernel 5.19
- Done - add support for kernel 6.0.
- Done - add support for kernel 6.1.
- Info - no support needed for kernel 6.2
- Done - add support for kernel 6.3.
- Info - no support needed for kernel 6.4
- Done - delete unneeded files in the root directory of the driver after testing to see which were needed.
- Info - USB3 mode works well but requires a module parameters to be set. Note: In-kernel drivers autodetect.
- Info - WPA3 seems to work well.
- Done - add and populate docs folder.
- Done - add sign-install support to Makefile.
- Done - [PATCH] [bugfix][MP] fixed for config TRX mode (RF Tx Path)
- Done - revert [PATCH] [bugfix][MP] fixed for config TRX mode (RF Tx Path). Bad patch.
- Done - add manual installation and removal instructions to README.md.
- Done - add edit-options.sh support.
- Done - activate and test packet injection support.
- Done - autodetect ARCH appears to be working on the supported platforms.
- Done - add supplemental files and scripts.
- Done - add support for kernel 6.5.
- Done - tested managed mode WiFi 6 with 2.4 GHz and 5 GHz. Excellent.
- Done - fix UBSAN out of bounds error x 2
- Done - concurrent mode appears be working - limited testing.
- Info - no support needed for kernel 6.6
- Done - add support for kernel 6.7.
- Done - add support for LED.
List of things that appear to be broken or unfinished:
- Beamforming appears to be non-functional.
- Power saving is non-functional. (noted in release notes.)
- Many settings in Makefile will cause compilation to fail!
- With debug turned off, there are still unneeded reports in the log file.
ToDo:
- in-progress - improvements and additions to install-driver.sh and remove-driver.sh
- in-progress - need improvements and additions to docs to reflect WiFi 6 support
Help is welcome.
Note: There are a massive amount of additions and changes from the WiFi 5 class Realtek out-of-kernel drivers.
Summary: Managed mode appears to be solid. Monitor mode and AP mode have had minimal testing so the status is mostly unknown, Monitor mode may not work as desired in all situations but that is true of almost all Realtek out-of-kernel drivers. I think this is a driver that can be released to the public but the driver appears to still be in development by Realtek and is fragile right now.
Performance report Test using managed mode and 5 GHz DFS channel:

Performance Test on a RasPi4B running RasPiOS: (the lower speed is likely due to my RasPi4B running headless)
