Probably need to go further with this.
 - what about unreigster in vmxnet3_dev_stop
 - vmxnet3_interrupt_handler is then dead code, should it be #ifdef guarded?
 - and vmxnet3_dev_rx_queue_intr_enable/disable
 - and vmxnet3_enable_intr
 - and vmxnet3_configure_msix
 - and checks for rte_eth_intr_conf bits? in configure
