Let me answer to the set of questions raised:

- dual licensing: I am not ready to answer for legal. I will discuss with 
proper people and answer.

- code style: regardless of answer on question above, I intend to do Linux 
work and will not care about compatibility macros. I really dislike such 
macros, they do make code hard to understand.

- information sharing (driver-stack): good question indeed. I am currently 
evaluating it. This far, I think I will supply some standard link layer 
information per packet. Like rate, RSSI etc. For Tx, it will include also 
crypto key for hardware assisted encryption, type of protection (RTS/CTS 
etc.) I believe it should be sufficient. To prove it, I am going to write 
some dummy .11 driver that will be capable to simulate any Rx, with user 
interface for feeding packets. I will use this driver to debug stack.

It is complex issue to support all combination of job separation between host 
and NIC, I will choose some model like "NIC do almost nothing" and will 
develop around it.
