Is RFC 3610 the one that talks about CCMP ?

In the given RFC, there is mention in the introduction section that CCMP can
be extended to other block sizes.
If I want to implement 192,256 key lenght support , then does it require
support from hardware ? I am asking this question because i am assuming that
key length is not dependent on hardware .Please clarify .

Thank you very much for your prompt reply . It's helping me a lot to
understand the things faster. :)
