DMA setup lock timeout protection is added when DMA setup frames are received. It's a function outside the protocol and used to prevent SATA disk I/Os from being delivered for a long time. The default value is 100ms, it's too strict and easily triggered timeout when the disk is overloaded or faulty. Based on the average I/O latency of 300 disks, we adjust the value to 2.5s.
