Hi Pepe, In addition, you may want to consider the frame's lifetime, to ensure memory is used and released in a valid way. When sending, it may be de-referenced by DPDK and consequently a memory free may be tried. Hence, it is important that the raw buffer used for the ARP packet is allocated with a reference added (or, alternately, just add-ref to the packet and ensure it'll not be freed by DPDK directly).

Please look the rte_mbuf structure in the header files and let me know if you still have the confusion. There is a header and payload. Your raw frame will go in the payload.

For example if I have an ARP packet: void * arp_pkt how should this be converted to an rte_mbuf * for transmission, does a simple cast suffice ?
