- 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.
