Ok...I have documented how I got all this working using our product to
configure things.  I also included the various conf files that our tool
creates, so maybe it will be useful to others trying to set up and test
EAP-AKA and/or HS20.


I think maybe a few conf file options are only supported by patches that we
carry in our hostapd tree and have not gotten upstream yet.  Should be able to
safely comment those out, or can use my hostapd code tree:


If anyone has suggestions for improving the info on the EAP-AKA page, please
let me know.
