Sorry for being dense, I'm not sure I understand. Do you mean response when you
say receive? We never have both a request and a response outstanding to the
same remove GID with the same TID, do we?
I was meaning:
Request - response bit is 0
Response - response bit is 1
Send - outgoing MAD (may be request or response)
Receive - incoming MAD (may be request or response)
In your example, you had host A sending a request to B (I'll call transaction
1), and host B sending a request to A (transaction 2). Host A has one request
being sent, and another being received. An ACK from B to A must match with
transaction 1. A NACK from B to A can match with either transaction.
To match NACKs using the response bit implies that requests can only flow one
direction, and responses the other. This adds a policy that I don't think
should be part of the general MAD layer code.
