John Garry 9c81e2cf7b scsi: hisi_sas: send three identify before phy up ... When the v2 hw is attached with many disks through an expander, there may be OOB reset resulting in a PHY going down after the speed is negotiated (very low probability). This issue is resolved by modifying the link control registers to send three identify frames before the PHY is ready (according to 6.10.3.3.2 in SAS 3.0 spec) and close ready when the PHY is down.
