Hi Pim, nice work, started something like this long time ago but never reached the finish line.
Only one comment, can you make it generic instead of dpdk specific. i.e. - all code in vnet/ethernet - show dpdk transceiver -> show interface transceiver - expose dpdk read epprom trough vnet_device_class_t, similar to set_rss_queues_function or flow_ops_function.
