in OpenStack.

This release is part of the ocata release series.

1.4.0
^^^^^


New Features
************

* New port profiles have been added to describe vhostuser fast path
  VIFs. In particular fast path vhostuser ports can be used with ovs,
  linuxbridge and calico networks. Thus for each kind of network a
  dedicated port profile class has been defined.

* The vhostuser vif object has been modified to add the name of the
  vhostuser port. Previously to this modification, it was
  responsibility of ovs plugin to compute such name. This should not
  be necessary with this new field. Because of this new field the
  VIFVHostUser object version has been updated accordingly (to 1.1).

* In the ocata cycle support was added for setting the MTU of vhost-
  user port with ovs.

* vhost-user MTU support enable jumbo frames to be used with vhost-
  user interfaces.

* vhost-user reconnect is a new feature of qemu that allows a vhost-
  user frontend(e.g. qemu) to reconnect to a vhost-user backend (e.g.
  ovs with dpdk) in the event that backend is restarted while the
  interface is in use. vhost-user reconnect leverages qemu vhost-user
  server mode with ovs-dpdk in client mode. This configuration
  requires ovs 2.6 with dpdk 16.07 and qemu 2.7 or newer to function.
  When qemu server mode is used with older qemu versions such as 2.5,
  vhost-user will still function with ovs 2.6 and dpdk 16.07, however,
  reconnect functionality will not be available.


Bug Fixes
*********

* The use of contextlib and  with nested statements is deprecated.
  "with nested" statements are not python 3 compatible as with
  statement now directly support context managers. The use of
  contextlib and "with nested" statements has been removed from all
  unittests in favor of the @mock decorator syntax.


Other Notes
***********

* vhost-user MTU support requires ovs 2.6 or newer. On older
  versions of ovs, the MTU request will not be made and jumbo frames
  are not supported.
