I'm not sure if it's a bug either, but you're not the only one who noticed:
https://forum.openwrt.org/t/low-entropy-22-03-snapshot-change-in-kernel-entropy-pool-logic/129573

When I saw that, I check my entropy level and that was 256 too.

I *think* it's intentional; various commits in 'crypto' also in 5.10.y branch
