The reason for this wrong behaviour can be found in line 201 of avahi-core/iface-pfroute.c:
The Linux kernel assigns a configurable scope to each IP address which
we use to choose the proper IP address to publish. Apparently FreeBSD
doesn't have that. The current code in Avahi thus assumes global scope
for all addresses.
A workaround for FreeBSD might be to check the address prefix directly
and to set global_scope to 1 only if it isn't fe80:: or 169.254. (Explanation:
global_scope is a boolean which for each address should be 1 if the
address is "global", and 0 if it is "link-local").
