This is v2 of [1], enabling uncompressed 128b/132b UHBR SST. The first one was accidentally "RFC v0", and there have been a few iterations sent to CI trybot since, with various version numbers, so I expect everyone to get royally confused about the versioning here. Sorry. Anyway, unlike with [1], we get a picture on screen with this, so it must be perfect. Please review. :) BR, Jani.
