Is it some package repo for kernel 5.4.42?

I see 19.07 uses kernel 4.14, and 21 utilize 5.4.143.
There are no available repos in between, which made me sad.

I use custom-build firmware from David at mine Linksys WRT3200ACM - it's still ONLY stable one for WRT series, but it have kernel 5.4.42.

Did anyone have repo with kmods for this kernel version?

Did you check this user repo? (Can't remember nickname so I can't credit him but he's been awesome).
