    i40e: Add 10GBaseT support

    Add driver support for 10GBaseT device.

we have the following chunk of code in i40e_ethtool.c:

        case I40E_PHY_TYPE_10GBASE_SFPP_CU:
                ecmd->supported = SUPPORTED_10000baseT_Full;
                break;
        case I40E_PHY_TYPE_1000BASE_KX:
        case I40E_PHY_TYPE_1000BASE_T:
                ecmd->supported = SUPPORTED_Autoneg |
                                  SUPPORTED_10000baseT_Full |
                                  SUPPORTED_1000baseT_Full |
                                  SUPPORTED_100baseT_Full;
                ecmd->advertising = ADVERTISED_Autoneg |
                                    ADVERTISED_10000baseT_Full |
                                    ADVERTISED_1000baseT_Full |
                                    ADVERTISED_100baseT_Full;
                break;
        case I40E_PHY_TYPE_100BASE_TX:
                ecmd->supported = SUPPORTED_Autoneg |
                                  SUPPORTED_10000baseT_Full |
                                  SUPPORTED_1000baseT_Full |
                                  SUPPORTED_100baseT_Full;
                ecmd->advertising = ADVERTISED_Autoneg |
                                    ADVERTISED_10000baseT_Full |
                                    ADVERTISED_1000baseT_Full |
                                    ADVERTISED_100baseT_Full;
                break;
        case I40E_PHY_TYPE_SGMII:
                ecmd->supported = SUPPORTED_Autoneg |

I'm confused by the fact that 2 cases that by name are 100M and 1G parts
got bits saying that 10G is "supported" - was that intentional?
