** Summary changed:
- phy linkrate persists after deactivation
+ libsas: old linkrate advertised after phy disabled
** Description changed:
[Impact]
sysfs continues to expose a valid phy linkrate even after the phy has been
disabled.
[Test Case]
Using hisi_sas, a libsas-based driver:
(initramfs) cd /sys/class/sas_phy/phy-0\:0\:20
- (initramfs) cat negotiated_linkrate
+ (initramfs) cat negotiated_linkrate
12.0 Gbit
- (initramfs) echo 0 > enable
+ (initramfs) echo 0 > enable

[Regression Risk]
Impact is limited to drivers built on top of libsas.
