  The Session ID also needs to be defined for SIM and AKA, as per Jouni's 
comments.  That doesn't fit in with AKA' changes.

  It may also be worth re-examining EAP-TLS.  Modern certificates are getting 
large, and people are using longer certificate chains.  The result can be that 
initial EAP-TLS authentication takes many packets.  This has issues not just 
for latency, but also access point implementations.  Most implementations will 
drop an EAP session if it hasn't finished after 40-50 packets.

  I've seen people run into this issue with large certificates and long 
certificate chains.  It would be good to find a way to allow this use-case.
