RE: SMC2802W V2 (prism54 nitro)

Yes - everything ARM based is capable of running XM... Obviously the
compression rate is dependent on how much host "power" is available as
we do compression in the upper MAC (running in the driver) - 
For Access points, there are two distinct types - those that use an
external host Network Processor and those that use an integrated NPU/MAC
- We call the  later WiSoC (Wireless System on a Chip)... So Client to
client rates are always great (assuming a decent computer is used) and
AP rates are dependent on the power of the NPU. We have the best luck
with Xscale based routers as they have the most available Mips... But
everything is upgradeable with software to get this functionality if it
is g or a/g product.

Are the present chips capable of the NitroXM? From the product brief it
seems to be software update too, as was the old Nitro. That would be
very nice :)
