I'm also a bit confused here. I do see the new message definition, but
I'm not sure which the "profile index parameter" is in the new
message. I see the "WDS Profile Identifier" and "WDS PDP Context
Number" TLVs, but those are also available in the original Create
Profile request... so how is this command different? Just wondering.
