Yep, I saw this. Thanks for it.

I know of linux-wlan of
Of course I' d prefer using HostAP for all the reasons you mentionned in your 
other mail : 
	open source ;
	stable ;
	well written ;

In my little dream world I'd imagine that HostAP replaces the totality of the  
tertiary firmware.
That would be a convenient way for every people wanting to manage the whole 

But it seems not possible for reasons I'm not able to understand right now : 

	are RIDs a virtual notion only exported by secondary and tertiary
	 firmwares without real existence in the MAC processor ?
	why do we need absolutely a secondary or a tertiary firmware ?

	since the RAM downloading depends on primary firmware why can
	we redevelop all the funtionnalities in an external process like HostAP that
	is to say to make a whole replacement of the tertiary software by HostAP?

I'm in the process of signing a NDA with Intersil but they don't seem to be 
very motivated saying that their priorities are the asian market.
The problem they don't want to see (don't want to show us they can see?) is 
that most of the adapters reaching the european market are made in Ta?wan or 
China !
What I can see from my little point of view is that, if there is nobody to 
develop on that chipset in Europe or elsewhere except Asia, no product can be 
build upon it.
I think that's what one called "a strategic walkthrough".

I did that but I think I have to apply your patch first.

Thank you,
