            Bug ID: 236724
           Summary: igbX interfaces fail to switch active to inactive
                    state
           Product: Base System
           Version: 12.0-STABLE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: kern
          Assignee: bugs at FreeBSD.org
          Reporter: ncrogers at gmail.com

Since upgrading to 12.0-RELEASE / iflib I've noticed that my igbX interfaces
no longer go from status "active" to "inactive" (as reported by ifconfig)
when the Ethernet port is unplugged and loses link. The status lights on the
physical interface go out but ifconfig still reports active +
autoselect/1000baseT. An "ifconfig down" followed by "up", while its
unplugged, forces the link to recognize the "inactive" state. After the
down/up dance plugging the cable in again returns it to "active".

I have replicated this problem with a clean install of the latest 12-STABLE
snapshot as of today. The only configuration I've made was the usual
timezone, root password, etc. during install. The interfaces in this test
case have no IP address configurations.

This is possibly a duplicate of bug #228556, however I am unsure because the
description is confusing and I am not using a virtualization layer.

I've noticed this on multiple systems with the following Intel devices (as
reported by pciconf "device"):

I210 Gigabit Network Connection
I211 Gigabit Network Connection
Ethernet Connection I354

uname -a:
FreeBSD test.local 12.0-STABLE FreeBSD 12.0-STABLE r345358 GENERIC  amd64

ifconfig when igb2 is actually connected and active:

ifconfig when igb2 is disconnected (identical to above):
igb2: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500

        ether 00:90:0b:78:13:5a

It may be worth noting that I have observed this problem on two other systems
with igbX interfaces. pciconf for these is below.
