Thanks Marc, Matt, Kyle, and Stephen for your inputs!
I have a possibly good solution of splitting the mbuf into parts to correctly
mirror to multiple interfaces, else a fallback of copying the full payload into
a new mbuf.
Though the library doesn?t offer a standard method to copy, I can

Hello,
Is there a function in DPDK to completely clone a pkt_mbuf including the
segments?
I am trying to build a packet mirroring application which sends packet out
through two separate interfaces, but the packet payload needs to be altered
before send.
Thanks,
Padam
I'm fairly new to dpdk, so I may be completely out to lunch on this, but
here's an idea to possibly improve performance compared to a straight copy
of the entire packet. If this idea makes sense, perhaps it could be added
to the mbuf library as an extension of the clone functionality?
If you are
Hey Kyle,
That's one way you can handle it, though I suspect you'll end up with some
complexity elsewhere in your code to deal with remembering whether you
should look at the original data or the copied and modified data. Another
way is just to make a copy of the original mbuf, but have your
Since Padam is going to be altering payload, he likely cannot use that API.
The rte_pktmbuf_clone() API doesn't make a copy of the payload. Instead,
it gives you a second mbuf whose payload pointer points back to the
contents of the first (and also increments the reference counter on the
first so
