Can data frames be sent back to back with no primitives or idle dwords
between the EOF of one frame and the SOF of the next?

If the ACK for a Response frame is lost the target will resend the
Response frame in a new connection with the retransmit bit set. During
the 1ms the target is waiting for the ACK it is possible that the
Initiator sends a new command with the same tag. When the retransmitted
Response frame arrives how does the Initiator know which command it is
actually for?
