    ethtool: (uapi) Add ETHTOOL_PHY_LOOPBACK to PHYtunables

    3 types of PHY loopback are supported.
    i.e. Near-End Loopback, Far-End Loopback and External Loopback.

    Near-End Loopback:
    Transmitted data (TXD) is looped back in the PCS block onto the receive
    data signal (RXD). When Near-End loopback enable, no data is transmitted
    over the network. no data receive from the network.

    Far-End Loopback:
    This loopback is a special test mode to allow testing the PHY from link
    partner side. In this mode data that is received from the link partner pass
    through the PHY's receiver, looped back on the MII and transmitted back to
    the link partner.
    Data present on the transmit data pins of the MAC interface is ignored when
    using this test.

    External Loopback:
    An RJ45 loopback cable can be used to route the transmit signals an the
    output of the trnsformer back to the receiver inputs and this loopback will
    work at either 10 or 100 or 1000 Mbps speed.
    RJ45 Loopback cable created by conncting pin 1 to pin 3 and connecting pin
    2 to pin 6.
