Subject: [PATCH 1/1] ethtool: add the external transceiver status of the ixgbe fiber

When the the fiber transceiver of the ixgbe NIC is external, sometimes
it is necessary to get the present/absent status of the fiber transceiver
of the ixgbe NIC.

The steps to get the present/absent status:
The NIC enp1s0f0 is an external ixgbe fiber NIC.

ethtool enp1s0f0

...
        Port: FIBRE
        PHYAD: 0
        Transceiver: external(present) <---The transceiver is present.
        Auto-negotiation: on
        Supports Wake-on: d
...

Or
...
        Port: FIBRE
        PHYAD: 0
        Transceiver: external(absent) <---The transceiver is absent
        Auto-negotiation: on
        Supports Wake-on: d
...
