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)

All this sounds great. I (and others) will be reviewing, and hope to get this into netdev-2.6 very soon.

Thanks much,
