I will improve this comment. I have spoken to Yunfei, and his firmware have no
interlacing support (despite the reference list size being 32 entry, so
interlaced ready). Though he said this is something he'd like to work in the
future, after this patchset have been merged of course. Sot he purpose of the
FIXME was really to ease locating were the field parity information is being
lost.

Thanks, I have no strong opinion, though I think I'll use the second, with weak
rationale that is looks more like the original style.
