Mignon,
>From your question it is not clear if you are asking from a targets point 
of view or an initiators point of view. It's also not clear if you are 
asking about what happens if frame level retries are enabled or disabled. 
So given that lack of knowledge the answer to you question is yes you have 
to overwrite data that is retried even if it has been ACKed.
Bye for now,

SAS: transport layer: ACK lost
Hello,
If retries are enabled, and an ACK gets lost, then the transmitter 
retries, is it required for the receiver to overwrite the data that is 
retried even if it has ACK-ed all data in the previous connection? 
Thanks in advance,
Mignon Fernandez
