wpa supplicant porting

ok that explains it .. 

I have ap_scan = 2 only, as I am having some issues with a driver call
to get  WPA IE (read not working with stability (some issue in binary
of MAC layer I have from vendor, following up .. ))

In my case, association IE's are generated by driver only and I had
configured it for WPA, so it got associated and TLS started ..

and what are u saying makes sense also (why was I not thinking of this
earlier -;)) IE info only will have the protocol to be followed.

But, I would have expected this field to be somewhere as part of (TLS
/ EAPOL key exchanges time also ? )

may be, dont know  .. 
but interesting bug, which many developers might end up into (ex: if
they port like I did) and u might like to keep in mind,
that key exchanges could go really really ahead, failing at either GTK
stage or sometimes at 2/4 handshake with MIC failures,

and at which stage there is no way of logically concluding that its
wrong protocol being worked upon ..

just keep a note for urself may be ..

I shall release code soon perhaps, but noone seems to be needing it
anyways here ..  so I have my own sweet time I believe -;l)
