MT6000 custom build with LuCi and some optimization - kernel 6.6.x

link to udp out-of-order issues and daniel's reply. No solution was ever provided then. it was flagged on bpi-r4 thread. But I have also tested this on mt6000. and I believe afffect all mt7986 and mt7988 and potentially mt7981 as well.
