David Milburn 2dc0b46b5e libata: sata_down_spd_limit should return if driver has not recorded sstatus speed ... During hotplug, it is possible for 6Gbps link speed to be limited all the way down to 1.5 Gbps which may lead to a slower link speed when drive is re-connected. This behavior has been seen on a Intel Lewisburg SATA controller (8086:a1d2) with HGST HUH728080ALE600 drive where SATA link speed was limited to 1.5 Gbps and when re-connected the link came up 3.0 Gbps. This patch was retested on above configuration and showed the hotplugged link to come back online at max speed (6Gbps). I did not see the downgrade when testing on Intel C600/X79, but retested patched linux-4.14-rc5 kernel and didn't see any side effects from this change. Also, successfully retested hotplug on port multiplier 3Gbps link. tj: Minor comment updates.
