Build Update for ovsrobot/ovs
-------------------------------------

Build: #2235
Status: Failed

Duration: 27 mins and 2 secs
Commit: 9cc86d1 (series_157317)
Author: Yi Yang
Message: Use TPACKET_V3 to accelerate veth for userspace datapath

We can avoid high system call overhead by using TPACKET_V3
and using DPDK-like poll to receive and send packets (Note: send
still needs to call sendto to trigger final packet transmission).

>From Linux kernel 3.10 on, TPACKET_V3 has been supported,
so all the Linux kernels current OVS supports can run
TPACKET_V3 without any problem.

I can see about 30% performance improvement for veth compared to
last recvmmsg optimization if I use TPACKET_V3, it is about 1.98
Gbps, but it was 1.47 Gbps before.

Note: it can't support TSO which is in progress.

Changelog:
- v1->v2
 * Remove TPACKET_V1 and TPACKET_V2 which is obsolete
 * Add include/linux/if_packet.h
 * Change include/sparse/linux/if_packet.h
