Priority: 1
Section: 2.1.2 - 2.1.6
Rationale/Explanation of issue: 

The NAS-Session-Key AVP as currently specified does not
include means to transport initialization vectors for
encryption.

Requested change: 

One way to support IV's would be to have a new NAS-Key-Type
for them. This would make sense especially if the NAS
uses the received material as a master session key from
which the actual IV's are derived.

Alternatively, we could specify that the keying material
of cipher keys includes initialization vector material.
