These docs are now part of nova, so I'm retargeting this bug
accordingly.

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.
