Following a rework of dpdk network structures names [1], update the
concerned parts.
Ran Olivier script [2]:
sh prefix-net-rte.sh $(find -name "*dpdk*.c")
sh prefix-net-rte.sh $(find -name "*dpdk*.h")
sh prefix-net-rte.sh $(find -name "*rte*.c")
sh prefix-net-rte.sh $(find -name "*rte*.h")
travis: Make it possible to build against a dpdk branch.
Rework the build script so that we can pass branches and tags.
With this, DPDK_VER can be passed as:
- a string starting with refs/ which is understood as a git reference.
This triggers a git clone on DPDK_GIT (default value points to https://dpdk.org/git/dpdk) for a single branch pointing to this
reference (to save some disk),
- else, any other string which is understood as an official release.
This triggers a tarball download on dpdk.org.
Rather than patch the dpdk makefile and a template config file, we can
pass the -fPIC flag via EXTRA_CFLAGS.
This is more reliable than expecting the dpdk file names to be kept
unchanged.
util: implement count_1bits with Neon intrinsics or gcc built-in for aarch64.
Userspace datapath needs to traverse through miniflow values many times. In
this process, 'count_1bits' operation for 'Flowmap' significantly impact
performance. On arm, this function was defined by portable implementation
because gcc for arm does not support popcnt feature.
But in the aarch64, VCNT neon instruction can accelerate "count_1bits".
From Gcc-7, the built-in function is implemented with neon intruction.
In this patch, count_1bits function will be impelmented with gcc built-in
from gcc-7 on, and with neon intrinsics in gcc-6.
Performance test was run in two aarch64 machines. In the NIC2NIC test, one
tuple dpcls lookup case achieves around 4% throughput improvement and
10(average) tuples case achieves around 5% improvement.
This patch updated acinclude.m4 so that OVS can be compiled on
5.0.x kernels.
This patch also updated travis files so that 5.0.x kernel versions
are used during travis test builds.
Besides, NEWS and releases.rst are also updated to reflect this
new support.

net: core: dev: Add extack argument to dev_change_flags()
Upstream commit:
commit 567c5e13be5cc74d24f5eb54cf353c2e2277189b
Author: Petr Machata <email address hidden>
Date: Thu Dec 6 17:05:42 2018 +0000
net: core: dev: Add extack argument to dev_change_flags()
In order to pass extack together with NETDEV_PRE_UP notifications, it's
necessary to route the extack to __dev_open() from diverse (possibly
indirect) callers. One prominent API through which the notification is
invoked is dev_change_flags().
Therefore extend dev_change_flags() with and extra extack argument and
update all users. Most of the calls end up just encoding NULL, but
several sites (VLAN, ipvlan, VRF, rtnetlink) do have extack available.
Since the function declaration line is changed anyway, name the other
function arguments to placate checkpatch.

datapath: Backport the removal of __tcp_checksum_complete()
Upstream commit 6ab6dfa6bb500f5cbb9b7a0f23a1613417ca2d12 ("net: get
rid of __tcp_checksum_complete())" deleted __tcp_checksum_complete()
and caused compilation failure for OVS on newer kernels.
This patch fixes it by using __skb_checksum_complete(), which is
100% the same with __tcp_checksum_complete().

OVS: remove use of VLAN_TAG_PRESENT
This is a minimal change to allow removing of VLAN_TAG_PRESENT.
It leaves OVS unable to use CFI bit, as fixing this would need
a deeper surgery involving userspace interface.
