Title:
  Flavors in Administrator Guide - confusing description for rxtx factor

Status in OpenStack Compute (nova):
  Confirmed

Bug description:
  - [x] This doc is inaccurate in this way: ______

  The RXTX Factor description currently states:

  "Optional property allows created servers to have a different
  bandwidth cap than that defined in the network they are attached to.
  This factor is multiplied by the rxtx_base property of the network.
  Default value is 1.0. That is, the same as attached network. This
  parameter is only available for Xen or NSX based systems."

  The compute API reference has a better and more accurate description:

  https://developer.openstack.org/api-ref/compute/?expanded=create-
  flavor-detail#create-flavor

  "The receive / transmit factor (as a float) that will be set on ports
  if the network backend supports the QOS extension. Otherwise it will
  be ignored. It defaults to 1.0."

  The admin guide description is really talking about nova-network and
  the xen virt driver, which is not untrue, but is a bit confusing (I
  don't know where the NSX part comes from).

  But the way this is used with neutron in nova is on the port if the
  QOS extension is enabled. Nova will likely deprecate this field in the
  flavor resource since nova-network is deprecated and if you're doing
  QOS on ports you should be doing that via the networking service, not
  the compute service flavors.
