Build Update for tmakita/ovs

Build: #40
Status: Failed

Duration: 42 mins and 22 secs
Commit: 6beddaa (xdp_offload_v1)
Author: Toshiaki Makita
Message: bpf: Add reference XDP program implementation for netdev-offload-xdp

Currently only supports very basic keys and output action.
We cannot support many keys/actions at the same time because the BPF
verifier has 1M insn limitation.  So the plan is to add config options
to skip compilation for keys/actions as well as adding more keys/actions.
Users of this reference program can choose only their needed
keys/actions by config options. This also minimizes the hash-table key
size, which reduces cache misses and boost the performance.

This program requires clang/llvm >= 9, libbpf >= 0.0.4 for BTF-defined
maps, and kernel >= 5.3 for BPF bounded loop.

FIXME: Temporarily using HAVE_AF_XDP switch to enable BPF programs

TODO: Install the XDP program somewhere (maybe /usr/lib/openvswitch/bpf?).
