When the target receives a NACK PDU, it re-sends the last sent PDU. ACK PDUs are received by the target as a reply from the initiator to chained I-PDUs. There are 3 cases to handle: - If the target has previously received 1 or more ATN PDUs and the PNI in the ACK PDU is equal to the target PNI - 1, then it means that the initiator did not received the last issued PDU from the target. In this case it re-sends this PDU. - If the target has received 1 or more ATN PDUs but the ACK PNI is not the target PNI - 1, then this means that this ACK is the reply of the previous chained I-PDU sent by the target. The target did not received it on the first attempt and it is being re-sent by the initiator. The process continues as usual. - No ATN PDU received before this ACK PDU. This is the reply of a chained I-PDU. The target keeps on processing its chained I-PDU. The code has been refactored to avoid too many indentation levels. Also, ACK and NACK PDUs were not freed. This is now fixed. Signed-off-by: Thierry Escande <thierry.escande@collabora.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com> |
