Specifically, there isnew R_ER code differences for command and data FISes. Changes are as follows: 1) 0x16 now additionally indicates an R_ERR received for a COMMAND FIS being sent to a SATA target. 0x16 for SSP still indicates a NAK received for a COMMAND frame. Fix is to retry TC to be compliant with SATA spec or ensure proper error handling of return value (not spec compliant I don't believe). 2) 0x1B was previously called DONE_BREAK_RCVD for STP and DONE_LL_ABORT_ERR for SSP. Now it is universally called DONE_LL_ABORT_ERR. This is purely a superficial change. 3) 0x32 is no longer a reserved code. Now it indicates DONE_CMD_SDMA_ERR for STP/SSP. There was a fatal error on the SDMA for a command IU (includes Raw frames). Consider retry, but at a minimum gracefully fail the request. 4) 0x33 is no longer a reserved code. Now it indicates DONE_CMD_LL_ABORT_ERR for SSP. There was a break receivd during transmission of a command IU. Consider retry, but at a minimum gracefully fail the request.
