Hi Ilya,
Thanks for such a detailed review!
I wasn't thinking about making all "make check-afxdp" test cases
passed because there are some errors not related to XDP.
But since you've done lots of investigation, let's fix all and make it passed.

The patch introduces experimental AF_XDP support for OVS netdev.
AF_XDP, the Address Family of the eXpress Data Path, is a new Linux socket
type built upon the eBPF and XDP technology. It is aims to have comparable
performance to DPDK but cooperate better with existing kernel's networking
stack.
