--- Comment #6 from Marek Zarychta <zarychtam@plan-b.pwste.edu.pl> ---
Please let me put my two cents in.=20

I confirm this regression, but it's not 100% reproducible. I noticed two fa=
cts
after the upgrade from 13.2-STABLE to 14.0-STABLE:

1. Messages like "arp: 00:aa:bb:cc:dd:ee trying to modify permanent entry f=
or
w.x.y.z on vlanQ" disappeared from Syslog even though the
net.link.ether.inet.log_arp_permanent_modify parameter is set to 1.

2. When traffic from an IP address protected by a static ARP entry is recei=
ved
from a spoofed host with the same IP address that violates this policy, the=
 ARP
entry for that IP address looks a bit strange:
? (w.x.y.z) at aa:bb:cc:dd:00:11 on vlan2 expires in -1708011502 seconds
[vlan],
but when the bogus traffic stops, the entry looks as expected
? (w.x.y.z.) at aa:bb:cc:dd:00:11 on vlan2 permanent [vlan].
