I am not sure if this is affecting me or is it for everybody. I had
defined in /boot/loader.conf, however it was never set in FreeBSD 12 (in 11.2 it was ok) and
came out as 1. I had to move net.add_addr_allfibs=0 from /boot/loader.conf to /etc/sysctl.conf for it to work. HTH.
Code:
net.add_addr_allfibs=0
Code:
sysctl net.add_addr_allfibs
