net: phy: microchip: lan87xx: reinit PHY after cable test

2024-07-18T11:22:38Z

[ Upstream commit 30f747b8d53bc73555f268d0f48f56174fa5bf10 ] Reinit PHY after cable test, otherwise link can't be established on tested port. This issue is reproducible on LAN9372 switches with integrated 100BaseT1 PHYs.

net: phy: dp83tg720: get master/slave configuration in link down state

2024-06-27T11:52:26Z

commit 40a64cc9679540ff7c46ecc51178b07d42abbb1c upstream. Get master/slave configuration for initial system start with the link in down state. This ensures ethtool shows current configuration. Also fixes link reconfiguration with ethtool while in down state, preventing ethtool from displaying outdated configuration. Even though dp83tg720_config_init() is executed periodically as long as the link is in admin up state but no carrier is detected, this is not sufficient for the link in admin down state where dp83tg720_read_status() is not periodically executed. To cover this case, we need an extra read role configuration in dp83tg720_config_aneg().

net: phy: mxl-gpy: Remove interrupt mask clearing from config_init

2024-06-27T11:52:22Z

[ Upstream commit c44d3ffd85db03ebcc3090e55589e10d5af9f3a9 ] When the system resumes from sleep, the phy_init_hw() function invokes config_init(), which clears all interrupt masks and causes wake events to be lost in subsequent wake sequences. Remove interrupt mask clearing from config_init() and preserve relevant masks in config_intr().

net: sfp: enhance quirk for Fibrestore 2.5G copper SFP module

2024-06-27T11:52:13Z

[ Upstream commit cd4a32e60061789676f7f018a94fcc9ec56732a0 ] Enhance the quirk for Fibrestore 2.5G copper SFP module. The original commit e27aca3760c0 ("net: sfp: add quirk for FS's 2.5G copper SFP") introducing the quirk says that the PHY is inaccessible, but that is not true. The module uses Rollball protocol to talk to the PHY, and needs a 4 second wait before probing it, same as FS 10G module. The PHY inside the module is Realtek RTL8221B-VB-CG PHY. The realtek driver recently gained support to set it up via clause 45 accesses.

net: sfp: Always call `sfp_sm_mod_remove()` on remove

2024-06-21T12:40:20Z

[ Upstream commit e96b2933152fd87b6a41765b2f58b158fde855b6 ] If the module is in SFP_MOD_ERROR, `sfp_sm_mod_remove()` will not be run. As a consequence, `sfp_hwmon_remove()` is not getting run either, leaving a stale `hwmon` device behind. `sfp_sm_mod_remove()` itself checks `sfp->sm_mod_state` anyways, so this check was not really needed in the first place.
