Stefano has been kind to open

    Bug 1295423 - Unstable network link using bond mode = 4
    https://bugzilla.redhat.com/show_bug.cgi?id=1295423

which we fail to reproduce on our own lab. I'd be pleased if anybody who
experiences it, and their networking config to the bug (if it is
different). Can you also lay out your switch's hardware and
configuration?
