Anne, the issue I have with calling out NSX is in "This parameter is only available for Xen or NSX based systems." - there is nothing specific about NSX or the vmware driver for the rxtx_factor in nova, so it's just kind of weird. If you have that flavor set it's global to all compute driver backends when using neutron in nova. That's why I think the more generic description from the compute API reference is better.
