Dear DPDK devs,
We are using DPDK as the backend target of a P4 pipeline
(https://github.com/p4lang/p4-dpdk-target
<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:
Why would it *require* an xor hash function in DPDK?
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
