Identify Address Frame
The Identify Address Frame format is used for the identification sequence. The Identify Address Frame is sent after
the PHY reset sequence completes. The Identify Address Frame format is defined as follows:

CRC
 Device Type is set to 001b to indicate that this drive is an "End Device"
 Address Frame Type is set to 00b to indicate that this is an IDENTIFY
 Reason indicates the reason for link reset sequence as defined in Table 35
 Initiator Port bits is set to 000b since this device is a target device only
 Target Port bits is set to 100b since this device is a SSP target device only
 Device Name contains Target Device Identifier
 SAS Address contains the port identifier of the SAS port transmitting this frame
 PHY Identifier contains the PHY identifier of the PHY transmitting this frame
 Persistent Capable is set to 0b to indicate the drive does not support persistent connections
 Power Capable is set to 00b to indicate drive does not issue PWR_REQ or PWR_DONE, and does not respond
to PWR_GRANT
 Slumber Capable is set to 0b to indicate drive does not support slumber power PHY mode
 Partial Capable is set to 0b to indicate drive does not support partial power PHY mode
 Inside ZPSDS Persistent: set to 0b since this is an "End Device"
