[Impact]
SATA disks may be unusable
will not be usable when:
- The disk is connected through a SAS expander
- Controller uses a libsas-based driver (mvsas, aic94xx, hisi_sas)
- link rate between expander & disk is greater than link between controller and expander
[Test Case]
See conditions in "Impact"
[Fix]
cec9771d2e954 scsi: libsas: Support SATA PHY connection rate unmatch fixing during discovery
[Regression Risk]
Impact is restricted to drivers that use libsas: mvsas, aic94xx & hisi_sas.
Code change is all within an "if" statement that meets these restrictions.
A bug in this code could possibly reduce the speed of an otherwise working disk connection. |

- Controller uses a libsas-based driver (mvsas, aic94xx, hisi_sas)
- link rate between expander & disk is greater than link between controller and expander
This is unlikely to occur in any production environment, but has occurred in early silicon testing. Fixing this would be helpful in those environments.
