Attached is the patch against 2.6.11-rc3-mm1 that adds the ieee80211 
subsystem used by the ipw2100 and ipw2200 projects.

I'll be sending out the patches for ipw2100-1.0.0 and ipw2200-1.0.0 that 
use thist stack to the list on Monday.

In terms of what the stack currently does:

* HW independent -- it only knows about 802.11 data and structures
* Performs an 802.3 <-> 802.11 transform for data Tx/Rx
* Host based support for fragmentation, WEP, and WPA using the kernel's 
crypto functions
* Beacon and probe response collection and parsing
* Default implementation of some of the WE handlers that can be managed 
without hardware knowledge

We are working to merge in Dave Miller's p80211 code into the ieee80211 
subsystem so that it hooks into the kernel as a true network layer as 
opposed to a mutated offspring of ethernet. 

Once that is done, hopefully the skb to txb code can be reworked and 
802.11 fragments can be treated either as normal skbs, or skbs can be 
modified to directly support them (ideally so that encrypted 802.11 
frames in support of IP packets can be cached by the stack instead of 
having to be re-encrypted on TCP retries)

Support for HW/FW crypto and fragmentation offload, in a HW independent 
fashion, is also on the short-term list.

When you look through the patch you'll likely notice the #ifdef 
NOTYET/#endif sequences surrounding portions of code from the hostap 
project.  Portions of this subsystem were based on an earlier version of 
the hostap project.  Those areas that weren't directly supported by the 
ipw* projects weren't ported to be completely hardware independent 
(since I don't have the hardware to test it), and so are still wrapped 
in the ifdefs.  These sections mainly cover support for MASTER and WDS 
modes.

Anyway, please let me know what you think.  Hopefully I built the patch 
right...

Thanks,
James
