- [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.
