CRC bytes will be add by HW, it is totally transparent for user.

I think it would be much more confusing to make user account for CRC bytes.
Let say when in DPDK you form a packet and send it out via rte_eth_tx_burst()
you specify only your payload size, not payload size plus crc bytes that HW will add for you.
