I recently got a H68K and was disappointed in the state of current OpenWRT forks for device, I had issues trying to use builds generated with the LinkStar/Lean forks (Broken 1Gb LAN ports/Sketchy feeds) so i made a clean fork that generates a working build and uses official feeds. Currently my git is based off OpenWRT's master branch and will be kept up to date for the near future, I will be preparing a v22.03.4 branch when i got some more time.. Hopefully this will help people actually make use of the HW.
If you have issue with OPKG use command sed -i -re 's/^(option check_signature.*)/#\1/g /etc/opkg.conf' .. Will fix this in next build.
