stable/12 - netstat -g IPv4 Virtual Interface Table data wrong

[Özkan KIRIK]

Hello,

I opened 2 bug reports about FreeBSD stable/12.
(https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=246626 and
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=246626)

I'm not runnging any daemons on system. No multicast software or
router running. But netstat output is scrambled.


I checkout latest sources from stable/12
(svn.freebsd.org/base/stable/12) and rebuild kernel. After reboot,
netstat -g output and multicast vif registration problems occured.

As you can see below, netstat -g output, scrambled. Thresh is too
high, Local addresses and counters are wrong. I think there is a
corruption in kernel.

There is no problem on FreeBSD 12.1-p5 system. But stable/12 is corrupted.
