As far as I know Alexei and Daniel are OK with the idea.
But better to let them reply here.

I suggest we think about a way to package the kernel BPF JIT
for userspace usage (not only DPDK) as a library.
I don't understand why the DPDK JIT should be different
or optimized differently.
The only real issue I see is the need for a dual licensing BSD-GPL.
