JIT like lua might also not work because you need to rewrite OVS to support it. I don't think that it will be accepted.

And it looks like it's problem in OVS, not in ODP. I.e. OVS should allow to use library functions for fast path (where inlines are critical). I.e. not just call odp_packet_len(), but move hole OVS function to dynamic library.

GCC has some experimental JIT support, but I think it would be a lot
of work to use it, and I don't know how stable it is.

The LLVM support is probably more advanced.
