[PATCH net-next 0/3] Preserve PSE PD692x0 configuration across reboots
From: Kory Maincent
Date: Tue Sep 30 2025 - 05:13:39 EST
From: Kory Maincent (Dent Project) <kory.maincent@xxxxxxxxxxx>
Previously, the driver would always reconfigure the PSE hardware on
probe, causing a port matrix reflash that resulted in temporary power
loss to all connected devices. This change maintains power continuity
by preserving existing configuration when the PSE has been previously
initialized.
