Dear DPDK devs,

We are using DPDK as the backend target of a P4 pipeline (
https://github.com/p4lang/p4-dpdk-target). A recent issue we are trying to
solve is to support a naive XOR hash (something like this
<https://github.com/p4lang/behavioral-model/blob/b7a5c105e5c21414ac07f7f2879b45c000ab2aa4/src/bm_sim/calculations.cpp#L380-L399>)
in this pipeline. This requires an XOR hash implementation in DPDK. I have
the following questions:

   1. Is there already an XOR hash implementation in DPDK? I haven't found
   it myself, but I could have missed it.
   2. If it doesn't exist, I'm willing to contribute one, as the
   implementation is quite straightforward. But I might need your help on
   where to put the code, as I'm not that familiar with the code organization.

Any help would be appreciated!

Thanks,
Bili
