--- Comment #11 from Andriy Gapon <avg at FreeBSD.org> ---
Not sure if that's relevant, but one thing I noticed is that the converted
driver lost handling of rxcd->error field.
The old code would do:
        if (rxcd->error) {
                rxq->vxrxq_stats.vmrxs_ierrors++;
                m_freem(m);
                return;
        }

But in the iflib world the error is simply ignored.
