How is this different than GetNegotiatedProtocol?

Based on the documentation, it WasNpnNegotiated == false is the same as
GetNegotiatedProtocol == kProtoUnkown, and vice versa.

[Ryan Hamilton, 2012/07/11 23:37:25]

I believe there is a distinction, though perhaps it is not an important
distinction.  But I think that WasNpnNegotiated can return true even if both
sides did not agree on protocol, and hence kProtoUnknow will be returned from
GetNegotiatedProtocol.
