"sparse" says:
../lib/nx-match.c:100:63: warning: constant 0xffffff80ffffffff is so big it
is unsigned long long
so I'd suggest adding a ULL suffix there (even though the warning does
make me just think "duh").
While reading nxm_field_by_header() I realized that we've got a terrible
existing mistake in our hashing. Ugh. I'll send a fix, which we'll want
to pre-apply (and maybe backport).
