Not really. In general, there's a lot more to it. Depending on which part
you use, you may or may not need to provide the MAC level
interface in software. There are a handful of newer parts with either open
or reverse engineered interfaces one could start from, but
it's a non-trivial effort. A lot of the embedded capable parts hook up via
SPI or SDIO, so there is a somewhat platform specific element
in many cases as well.

A lot of the chips include it in their internal firmware.
