    ethdev: reject conflicting Tx offload configurations

    When an ethdev port is configured for fast mbuf release, the driver can
    use a Tx burst function relying on the fast mbuf release preconditions.
    Thus, also configuring this port or a queue on the port for transmitting
    segmented packets is prohibited.
    Checks for these conflicting configurations have been added to the ethd=
ev
    library, so the drivers don't have to implement them.
