[c-nsp] 1252ag backwards compatibility

Yes, backward-compatibility can be prevented by running Greenfield mode, but
I'm not sure if that's possible on the Cisco 1252.

802.11n clearly has the capability for a higher PPS than 802.11b/a/g if you
fix the packet size, but I'm not sure what you mean about the processors.

Can it be prevented, i.e, configuring 1252 to only run 802.11n, even
in WDS mode ?
We are hoping that 802.11n can improve on Wi-Fi tradition of having
low pps rate, which is due to the sum of the 802.11b/a/g standard
and low speed processors on the devices.
