Just from a quick glance:

- drivers/net/wireless/libertas/radiotap.h file with a lot of constants
  already defined elsewhere (and not respecting kernel coding style,
  either)
- regulatory domain management (already in ieee80211, in progress for
  d80211)
- the full authentication and association state machine (or am I
  understanding it wrong?)

And I'm omitting things like

or those ENTER and LEAVE statements in each other function,
non-conforming coding style, comments like "All rights reserved" or
"This software file (the "File") is distributed by Marvell
International Ltd.", a lot of duplicated code, etc. I stopped looking
at it in the half, sorry.
