The retransmission is handled at the A-PHY level and is transparent to the upper layer. A-PHY has a retransmission buffer to handle camera stream with up to three retries. The net application data throughput already takes care of the retransmission; no additional buffering is required at the MIPI CSI-2 level. More information can be found in the MIPI A-PHY specification.
