--- Comment #1 from jcaplan at blackberry.com ---
After a bit more investigating, all segments are discarded on the target.

in vmxnet3_isc_rxd_pkt_get(), this condition is reached for all incoming
packets with large MTU:


        if (__predict_false(rxcd->error)) {
                rxc->vxcr_pkt_errors++;
                for (i = 0; i < nfrags; i++) {
                        frag = &ri->iri_frags[i];
                        frag->irf_len = 0;
                }
        }


As far as I can tell I've done everything on the host side with vmware to
configure MTU properly.
