Ok thanks a lot Richardson. I got your point. What confused me was that the
size of MBUF and the maximum size are all passed to
'rte_mempool_create' . rte_pktmbuf_alloc
has only one parameter , a pointer to the mbuf pool. I got it cleared now.
Thanks for your valuable time. Can you answer my other
Thanks on the reply Richardson. You did mention something like "Don't
forget that when you get the mbuf from rte_pktmbuf_alloc, you also need to
set the length value to the appropriate size." .
Like I'm allocating the mbuf using rte_mbuf . The rte_mempool_create has
already set the maximum packet
Hello friends,
I'm trying to print the ether_type for a packet that I captured from a port
on my machine. Suppose 'm' holds the packet. 'm' is of type 'struct
rte_mbuf'. Intels API reference for DPDK says 'ether_type' is of uint16_t.
I used the following code to retrieve ether_type.
void * eth_ty
Thank you very much Richardson for your valuable reply. But is there
another way of doing it using the rte_pktmbuf_append / rte_pktmbuf_prepend ?
Can you please tell me on how to do that ?
Regards

Hello friends,
As of now... I know on how to create an ipv4 header using the 'struct
ipv4_hdr'.
My requirement is to craft a packet and sent it via 'rte_eth_tx_burst'.
I know that there should be an 'ether_hdr' created before, the packet could
be sent.
Could someone help me on how to set the addre

Hi All,
I'm trying to implement the "time triggered send" as an extension of the
PMD driver of the i210 controller.
Are there ans application guides or sample codes showing how to handle
the specific timer(s) of the i210 ?
This nice feature isn't well documented ...
Best Regards
Armin Steinhpf
