[ovs-dev,v5] netdev-afxdp: add new netdev type for AF_XDP.

The patch introduces experimental AF_XDP support for OVS netdev.
AF_XDP is a new address family working together with eBPF/XDP.
A socket with AF_XDP family can receive and send raw packets
from an eBPF/XDP program attached to the netdev.
For details introduction and configuration, see
Documentation/intro/install/afxdp.rst

Bleep bloop.  Greetings William Tu, I am a robot and I have tried out your patch.
Thanks for your contribution.

I encountered some error that I wasn't expecting.  See the details below.

Thanks, William and Yi-Hung.

Before I installed libbpf, "configure" failed, even without
--enable-afxdp:

    config.status: error: Something went wrong bootstrapping makefile fragments
        for automatic dependency tracking.  Try re-running configure with the
        '--disable-dependency-tracking' option to at least be able to build
        the package (albeit without support for automatic dependency tracking).
    See `config.log' for more details

I'm attaching the full config.log in case it is helpful.

I would recommend adding a sentence or two to afxdp.rst explaining why
someone would want to use AF_XDP.  Currently it is kind of there
("...much better performance than AF_PACKET.") but it is not called out
very well.  Maybe something along the lines of saying that it aims to
have comparable performance to DPDK but cooperate better with existing
kernel mechanisms.  Otherwise, someone who is new to OVS or to AF_XDP
will not have any idea of the context.

In afxdp.rst, I'd also recommend explaining why the recommended kernel
config options are recommend.  I'd guess that the BPF_JIT ones are there
for performance and XDP_SOCKETS_DIAG is for debugging, but it'd be nice
to say so.

s/Fist/First/:
+Fist, clone a recent version of Linux bpf-next tree::

In the instructions for installing libbpf, I had to run plain "ldconfig"
by hand before the library showed up in "ldconfig -p" output.

I'm not sure everyone knows the system include path, so you might add
something like "e.g. /usr/local/include/bpf/xsk.h" to this note:
+.. note::
+   Make sure xsk.h is install in system's library path

"make install_headers" failed to install libbpf_util.h for me, so the
build failed.  I installed it by hand and it worked OK after that:

    blp@sigill:~/nicira/bpf-next/tools/lib/bpf(0)$ sudo cp libbpf_util.h /usr/local/include/bpf/

I didn't test AF_XDP at runtime, but I did verify that the binary
linked and started up OK.

I had to apply the following patch to suppress warnings from sparse and
GCC 8.x:
