+# 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

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