[PATCH] lldp: Fix clang warning.

Clang-3.7 generates warnings such as the following:
../lib/ovs-lldp.c:394:19: error: address of array 'hardware->h_ifname'
will always evaluate to 'true' [-Werror,-Wpointer-bool-conversion]

This value is fetched from a netdev, which as far as I can tell must
always have a non-NULL name. Simplify this code.

+### Q: How do I configure a DPDK port as an access port?
+A: Firstly, you must have a DPDK-enabled version of Open vSwitch.
+   If your version is DPDK-enabled it will support the --dpdk
+   argument on the command line and will display lines with

[PATCH] netdev-dpdk: add dpdk vhost-user ports

This patch adds support for a new port type to the userspace
datapath called dpdkvhostuser. It adds to the existing
infrastructure of vhost-cuse, however disables vhost-cuse ports
as the default port type, in favour of vhost-user ports.
vhost-cuse 'dpdkvhost' ports are still available and can be
enabled using a configure flag, steps for which are available

A new dpdkvhostuser port will create a unix domain socket which
when provided to QEMU is used to facilitate communication between
the virtio-net device on the VM and the OVS port on the host.

[PATCH net-next V8 0/2] openvswitch: Add support for 802.1AD

Add support for 802.1AD to the openvswitch kernel module (Version 8.)

Please replace version 7 submitted on April 25, with this patch.
Version 8 has changes based on the review by Pravin Shelar of V7 and a fix
to flow.c to initialize the ctci in the flow key.

There was one recommended change from the review that was not made in this 
patch about a double check for vlan headers. The rationale for not making
that change will be explained separately.

Although the Open Flow specification specified support for 802.1AD (qinq)
as well as push and pop vlan headers, so far Open vSwitch has only
supported a single tag header. This patch addresses adds 802.1ad to the
Linux kernel openvswitch data path.

This patch is version 8 of the patch andccompanies user space version 7 of
the patch previously submitted separately to openvswitch dev list.

For discussion, history  and previous versions, of the kernel patch,
see the OVS dev mailing list, openvswitch.org/pipermail/dev/..

  Add flow key field for ctag
  Flow handling, actions and vlan parsing for 8021AD

[PATCH ovn] controller: Set chassis for container port.

ovn-controller updates the chassis column of the Bindings table in
OVN_Southbound when a logical port appears on the local switch.  A
logical port that has a parent will never appear on a switch managed
by ovn-controller.  When a parent port appears, all child container
ports should be updated as being on that chassis, as well.
