DPDK and VPP

This is pain.

I'm not able to build dpdk / vpp for alpine aarch64.

DPDK

Testing with dpdk-testpmd. Does not seem to like the NIC layout we have here.

We get this error complaining when some NICs controlled by linux

Works only when all interfaces are handed over

VPP

Can't even build. The toolchain is messy. So many errors to plow through. I gave up.
