            Bug ID: 212283
           Summary: network watchdog timeout with some raw sockets usage
           Product: Base System
           Version: 11.0-RC1
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs@FreeBSD.org
          Reporter: mat@FreeBSD.org
                CC: freebsd-amd64@FreeBSD.org, re@FreeBSD.org
                CC: freebsd-amd64@FreeBSD.org

(it is for 11.0-RC2, but it also works on 11.0-RC1 and 11.0-RC2 is not in t=
he
list)

When I run ntraceroute -uOAM google.com (the host doesn't matter) (from
net/ntraceroute)

On my dev box, it does:
re0: watchdog timeout
re0: link state changed to DOWN
re0: link state changed to UP

On my poudriere build box, it does:
bge0: watchdog timeout -- resetting
bge0: link state changed to DOWN
bge0.666: link state changed to DOWN
[...more vlans]
bge0: link state changed to UP
bge0.666: link state changed to UP
[...more vlans]

I have no clue of what it really does, but it's bad.
