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: b...@freebsd.org
Reporter: ncrog...@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
