This version of EAP-GPSK draft seems to resolve the key derivation
questions I had apart from one detail: how is PL to be represented in
the "PL || PSK || CSuite_Sel || ..." construction? As a single octet? As
two octets in network byte order? For now, I just assumed it is only a
single octet.
In addition, I noticed that chapter 2 is defined CSuite_Sel incorrectly:
CSuite_Sel:
Ciphersuite selected by the client (1 octet or 7 octets)
This should be replaced with
Ciphersuite selected by the client (6 octets)
to match with chapter 7.2 ("Ciphersuites are encoded as 6-octet
arrays").
In addition, CSuite_SEL in 6.1.3 and 6.2.3 should have been CSuite_Sel
to remain consistent with the spelling in rest of the draft.
