Cast pointer to required struct pointer, for example for ipv4
struct ipv4_hdr *iph;
iph = (struct ipv4_hdr *)rte_pktmbuf_append(m, sizeof(struct ipv4_hdr));
and fill in fields.
Look in lib/librte_net/ directory.

Hai friends,
My requirement is to create a packet generator. So I could use
struct rte_mbuf * m;
to create a single packet holder. So how am I suppose to fill in the packet
details like the MAC source , destination and also the IP source ,
destination (in case of IPv4 packets).
Following the l2
Hi,
At first look at https://github.com/Pktgen/Pktgen-DPDK
If you need your custom app:
- alloc mbuf with rte_pktmbuf_alloc
- fill up L2-4 headers fields (look at rte_pktmbuf_append func for example)
- send packet via rte_eth_tx_burst

I dug deeper into the problem vmxnet-pmd not capturing packets. Whenever pmd
stops capturing, it does not respect the number of rxd. For example, I set rxd
to 512. The pkt mbuf mempool I allocate is 4482, which is much bigger than rxd.
I would expect ~512 mbufs to be removed from mempool at any

We had excellent technical discussions around network virtualization
at LPC13 last year and would love to provide the same forum at this
year's LPC again.
I believe this would be a good opportunity to discuss integration of
DPDK with the Linux net
