I wonder if this is a bug in sparse? the macro uses gcc magic to
expand to a constexpr.

You could also use __constant_cpu_to_be32 and similar instead.

But I admit I never liked the use of no-host endian in the constants..

Would be nice to see these fixed into an enum someday too

I usually discourage the extra horizontal whitespace, just causes patch churn to
keep it up (and clang-format won't do it automatically). Not sure if
there is a consensus on that though.

But looks fine to me.
