net: pcs: pcs-mtk-lynxi: report in-band capability for 2500Base-X

2026-01-22T04:01:03+00:00

It turns out that 2500Base-X actually works fine with in-band status on MediaTek's LynxI PCS -- I wrongly concluded it didn't because it is broken in all the copper SFP modules and GPON sticks I used for testing. Hence report LINK_INBAND_ENABLE also for 2500Base-X mode. This reverts most of commit a003c38d9bbb ("net: pcs: pcs-mtk-lynxi: correctly report in-band status capabilities"). The removal of the QSGMII interface mode was correct and is left untouched.

net: remove phylink_pcs .neg_mode boolean

2025-02-15T01:09:50+00:00

As all PCS are using the neg_mode parameter rather than the legacy an_mode, remove the ability to use the legacy an_mode. We remove the tests in the phylink code, unconditionally passing the PCS neg_mode parameter to PCS methods, and remove setting the flag from drivers.

net: pcs: lynxi: implement pcs_disable op

2023-08-22T02:08:57+00:00

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.

Update the Lynxi PCS driver to use neg_mode rather than the mode argument. This ensures that the link_up() method will always program the speed and duplex when negotiation is disabled.
