Build Update for williamtu/ovs-travis
-------------------------------------

Build: #194
Status: Passed

Duration: 1 hr, 5 mins, and 46 secs
Commit: 0b4aead (afxdp-v8)
Author: William Tu
Message: netdev-afxdp: add new netdev type for AF_XDP.

The patch introduces experimental AF_XDP support for OVS netdev.
AF_XDP, 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.  An AF_XDP socket receives and sends packets from an eBPF/XDP program
attached to the netdev, by-passing a couple of Linux kernel's subsystems
As a result, AF_XDP socket shows much better performance than AF_PACKET
For more details about AF_XDP, please see linux kernel's
Documentation/networking/af_xdp.rst

v1->v2:
- add a list to maintain unused umem elements
- remove copy from rx umem to ovs internal buffer
- use hugetlb to reduce misses (not much difference)
- use pmd mode netdev in OVS (huge performance improve)
- remove malloc dp_packet, instead put dp_packet in umem

v2->v3:
- rebase on the OVS master, 7ab4b0653784
  ("configure: Check for more specific function to pull in pthread library.")
- remove the dependency on libbpf and dpif-bpf.
  instead, use the built-in XDP_ATTACH feature.
- data structure optimizations for better performance, see[1]
- more test cases support
v3: https://mail.openvswitch.org/pipermail/ovs-dev/2018-November/354179.html

v3->v4:
- Use AF_XDP API provided by libbpf
- Remove the dependency on XDP_ATTACH kernel patch set
- Add documentation, bpf.rst

v4->v5:
- rebase to master
- remove rfc, squash all into a single patch
- add --enable-afxdp, so by default, AF_XDP is not compiled
- add options: xdpmode=drv,skb
- add multiple queue and multiple PMD support, with options: n_rxq
- improve documentation, rename bpf.rst to af_xdp.rst

v5->v6
- rebase to master, commit 0cdd5b13de91b98
- address errors from sparse and clang
- pass travis-ci test
- address feedback from Ben
- fix issues reported by 0-day robot
- improved documentation

v6-v7
- rebase to master, commit abf11558c1515bf3b1
- address feedbacks from Ilya, Ben, and Eelco, see:
  https://www.mail-archive.com/ovs-dev@openvswitch.org/msg32357.html
- add XDP mode change, implement get/set_config, reconfigure
- Fix reconfiguration/crash issue caused by libbpf, see patch:
  [PATCH bpf 0/2] libbpf: fixes for AF_XDP teardown
- perf optimization for batching umem_push/pop
- perf optimization for batching kick_tx
- test build with dpdk
- fix/refactor atomic operation
- make AF_XDP x86 specific, otherwise fail at build time
- lots of code refactoring
- add PVP setup in documentation
