Bug ID: 240658
Summary: iflib: Some if_igb(4) devices don't recognize/report
carrier loss.
Product: Base System
Version: 12.0-STABLE
Hardware: Any
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
Hello,
reported back in May 2018 with a Clarkville MAC:
https://lists.freebsd.org/pipermail/freebsd-net/2018-May/050497.html
Currently I see this again in 12.1-pro with Powerville (i211), while other
if_igb(4) NICs are not affected (i350).
I don't have a i217 handy to verify if this bug reoccured, or if my "not
reproducable anymore" was simply wrong.
Can anybody remember when/who worked on that issue?
This is a major issue, since if_lagg(4) clones depend on the link state
information and pulling a cable leads to interrupted communication – the
opposite of what if_lagg(4) should provide! i211 is a widely used on-board
server nic, so most likely many were affected by this issue if shipped with
12.1.
Thanks,
-Harry
