Is this function to get dev->data->port_id ?

"struct ark_adapter" is private date per eth_dev, it is possible to keep
port_id per ark, no need to keep whole array on each ark, if I am now
missing anything ...

Why not using RTE_LIBRTE_ARK_PAD_TX directly, but creating another macro?

Is it possible to handle RTE_LIBRTE_ARK_DEBUG_TX in log.h file to create
a ..LOG_TX macro and use it, instead of dealing here with new macros?

Why not include relevant headers, instead of these struct declarations.
