  MFC r180551.
    Fix VR_RXSTAT_RX_OK bit definition which lasted for more than 9
    years. All datasheet I have indicates the bit 15 is the
    VR_RXSTAT_RX_OK. The bit 14 is reserved for all Rhine family
    except VT6105M. VT6105M uses that bit to indicate a VLAN frame
    with matching CAM VLAN id.
    Use the VR_RXSTAT_RX_OK instead of VR_RXSTAT_RXERR when vr(4)
    checks the validity of received frame.
    This should fix occasional dropping frames on VT6105M.
