you to have multiple profiles per network. Not finished yet.
- hfa384x.h updates.
- additions to the MIB.
- Cleaned up wireless extension stuff a little bit.
- Rewrote part of the existing wireless extension code.
- Add the Microsoft MN510 device ID.
- Finally fix the 'crash on unload' problem for 2.2.x kernels with PCI.
Turns out the kcompat24 code wasn't quite complete. (Matthew Rush)
