This helper name is ambiguous.
Maybe the intent was to have a generic place holder for updates in
future releases.
But in this series, __rte_eth_rx_epilog is invoked only if a rx
callback is registered, under #ifdef RTE_ETHDEV_RXTX_CALLBACKS.

I'd prefer we call it a spade, i.e. rte_eth_call_rx_callbacks, and it
does not need to be advertised as internal.

Idem, rte_eth_call_tx_callbacks.
