Yes. These are state machine names. The "I" referers to initiator states, and "R"
means responder states. The number is the packet number sent in the exchange.

So STATE_QUICK_I2 is the second patcket on Quick Mode on the Initiator. Note
that a retry/retransmit would also be STATE_QUICK_I2.

When you see something like:

 	 STATE_MAIN_R1: sent MR1, expecting MI2

It means we are now in state MAIN_R1. W sent the Main Mode Response 1 packet. We
are expecintg the other end to send the Main mode Initiate second packet.
