Build Update for williamtu/ovs-travis
Duration: 44 mins and 38 secs
Commit: adff46f (afxdp-file-v2)
Author: William Tu
Message: netdev-afxdp: Enable loading XDP program.
Now netdev-afxdp always forwards all packets to userspace because
it is using libbpf's default XDP program, see 'xsk_load_xdp_prog'.
There are some cases when users want to keep packets in kernel instead
of sending to userspace, for example, management traffic such as SSH
should be processed in kernel.
The patch enables loading the user-provide XDP program by doing
$ovs-vsctl -- set int afxdp-p0 options:xdpobj=<path/to/xdp/obj>
So users can implement their filtering logic or traffic steering idea
in their XDP program, and rest of the traffic passes to AF_XDP socket
handled by OVS.
The xdp/xdp1.c is a sample C program and has to be compile using clang
under kernel's samples/bpf/. I don't know whether we should include
the C file in OVS, or we should include BPF bytecode, or simply not
providing any sample program in OVS.
