Subject: [PATCH 082/125] net: pcs: lynxi: implement pcs_disable op
|
|
|
|
When switching from 10GBase-R/5GBase-R/USXGMII to one of the interface
|
|
modes provided by mtk-pcs-lynxi we need to make sure to always perform
|
|
a full configuration of the PHYA.
|
|
|
|
Implement pcs_disable op which resets the stored interface mode to
|
|
PHY_INTERFACE_MODE_NA to trigger a full reconfiguration once the LynxI
|
|
PCS driver had previously been deselected in favor of another PCS
|
|
driver such as the to-be-added driver for the USXGMII PCS found in
|
|
MT7988.
