I discussed this with Alper, and we think that we do not need to use
the PANA-Auth-Request(q+1) as an acknowledgement for
PANA-Auth-Request(p).  Let the protocol run as it is should work fine 
as follows:

o PANA-Auth-Request(q+1) will be accepted by PAA and the EAP-Response
contained in the message will be passed to EAP authenticator.

o The EAP authenticator will send another PANA-Auth-Request(p+1) with
a new EAP-Request or a PANA-Bind-Request, but this messsage will be
queued by the PAA since there is an outstanding previous request
PANA-Auth-Request(p).

o PANA-Auth-Request(p) will be retransmitted and finally PAA receives
PANA-Auth-Answer(p), the queued message will be transmitted and the
protocol continues to run as expected.

Yoshihiro Ohba
