Hi Ben,

It looks like there's a patch in gerrit to convert the vpp API already. I
just noticed this now:
https://review.gerrithub.io/c/spdk/spdk/+/417056

I'm missing some background it seems. The 18.10+ VCL doesn't look thread
safe. I guess that was the reason for the changes to the vcl interface. Is
this patch planned for a certain release?

Thanks,
Jon

The only reason VPP hasn't been upgraded is that no one has done it yet. If
you'd like to tackle the upgrade, please do submit the patches. That would
be
great!

In general SPDK does have a number of backward compatibility requirements.
However, for VPP specifically, I don't see any downside to just doing a
wholesale upgrade this time. I don't think you need to maintain backward
compatibility with an older VPP.

Thanks,
Ben
