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

2024-06-27T11:49:07+00:00

[ 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: Always call `sfp_sm_mod_remove()` on remove

[ 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.

net: phy: Micrel KSZ8061: fix errata solution not taking effect problem

2024-06-21T12:38:16+00:00

[ Upstream commit 0a8d3f2e3e8d8aea8af017e14227b91d5989b696 ] KSZ8061 needs to write to a MMD register at driver initialization to fix an errata. This worked in 5.0 kernel but not in newer kernels. The issue is the main phylib code no longer resets PHY at the very beginning. Calling phy resuming code later will reset the chip if it is already powered down at the beginning. This wipes out the MMD register write. Solution is to implement a phy resume function for KSZ8061 to take care of this problem.

net: sfp-bus: fix SFP mode detect from bitrate

2024-06-16T11:47:30+00:00

commit 97eb5d51b4a584a60e5d096bdb6b33edc9f50d8d upstream. The referenced commit moved the setting of the Autoneg and pause bits early in sfp_parse_support(). However, we check whether the modes are empty before using the bitrate to set some modes. Setting these bits so early causes that test to always be false, preventing this working, and thus some modules that used to work no longer do. Move them just before the call to the quirk.

net: micrel: Fix lan8841_config_intr after getting out of sleep mode

2024-06-12T09:12:56+00:00

[ Upstream commit 4fb679040d9f758eeb3b4d01bbde6405bf20e64e ] When the interrupt is enabled, the function lan8841_config_intr tries to clear any pending interrupts by reading the interrupt status, then checks the return value for errors and then continue to enable the interrupt. It has been seen that once the system gets out of sleep mode, the interrupt status has the value 0x400 meaning that the PHY detected that the link was in low power. That is correct value but the problem is that the check is wrong. We try to check for errors but we return an error also in this case which is not an error. Therefore fix this by returning only when there is an error.

net: micrel: Fix receiving the timestamp in the frame for lan8841

2024-06-12T09:11:54+00:00

[ Upstream commit aea27a92a41dae14843f92c79e9e42d8f570105c ] The blamed commit started to use the ptp workqueue to get the second part of the timestamp. And when the port was set down, then this workqueue is stopped. But if the config option NETWORK_PHY_TIMESTAMPING is not enabled, then the ptp_clock is not initialized so then it would crash when it would try to access the delayed work. So then basically by setting up and then down the port, it would crash. The fix consists in checking if the ptp_clock is initialized and only then cancel the delayed work.
