There have been claims that Marvell's solution is especially
well-suited to the XO because it includes a processor.
I can still count the chips though, and Marvell is using 2.
That makes them no better than a 1-chip solution without
a processor, because one can just add a processor to a
softmac 1-chip solution.
I am glad that the Marvell stuff is on USB, where it can
not DMA right over the kernel. :-)

Being a tad less aggressive: CaFE, D-CON, and a PPC4xx
to turn a softmac wireless chip into fullmac.
