I think you should have asked re@ or this may get otherwise unnoticed...

I was kinda surprised with the fact that the spare fields are defined
as 'uint' and not something like 'u_int32_t' because the former is
less defined.  We should probably use u_int32_t instead for the spare
fields to avoid the ambiguity.

However, because all platforms that FreeBSD currently supports have
32-bit int (doing a quick grep of __UINT_MAX), I think the change does
not break KBI.  The added field does not break KPI.

Cheers,
