Hi,
I am not sure if I understand the question correctly, but there was a
change to the rte_mbuf structure with
patch ea672a8b1655bbb44876d2550ff56f384968a43b. It got rid of the pkt
member in rte_mbuf. Here is an example of how to fix it:
- eth_hdr = (struct ether_hdr *) mb->pkt.data;
+ eth_hdr = (struct ether_hdr *) mb->data;
Another way of answering your question is that it is "data" in rte_mbuf:
- struct rte_pktmbuf pkt;
+ /* valid for any segment */
+ struct rte_mbuf *next; /**< Next segment of scattered packet. */
+ void* data; /**< Start address of data in segment
buffer. */
+ uint16_t data_len; /**< Amount of data in segment buffer. */
