This should apply on little endian systems only I believe.

bz updated this revision to Diff 164573.Oct 20 2025, 5:03 AM

Add add counted_by_le() and counted_by_be() and make them
endian conditional. Apparently there's still supported big-endian
out there even though we do not support wireless drivers on it
currently.

This needs sys/endian.h ; will be included in the commit. Funny it worked on a local kernel compile but on a clean tinderbox it failed.
