net80211+atheros changes (updated)

[Sam Leffler]

http://www.freebsd.org/~sam/net80211+ath-20041013.tgz has an updated 
backport of the work I've done in Linux.

These changes are against current; they may apply against other recent 
branches but code will not compile because of recent additions to current.

To apply these changes to a clean current tree do something like:

cd /usr/src
tar zxf net80211+ath-20041013.tgz
sh doit

then rebuild modules and/or kernels.

Note that the 802.11 code has been broken up into multiple modules that 
either need to be built or specifed in your kernel config file.  Module 
dependencies should handle most issues on load. To get WEP support you 
need to specify

device wlan_wep

in your kernel config file or build the wlan_wep module.  Similarly for 
tkip and ccmp crypto support.

The tx rate control algorithm for the Atheros driver has broken out into 
a separate module.  As above you need ath_rate_onoe for the usual 
algorithm.  There is also an amrr algorithm that can be specified with 
ath_rate_amrr.

This version should include working crypto support for the ath driver. 
I have not tested other drivers; I expect wi to work in station mode but 
not in hostap mode.  This version should also have the functionality to 
support wpa_supplicant and hostapd as WPA supplicant and authenticator, 
respectively.

I'm not sure how much time I'll have to respond to issues so please dig 
first before asking for help.
