Monthly summary for 2025-05: Implemented a new Low Power Mode (LPM) status retrieval for SFP modules in sonic-platform-modules-accton via the get_lpmode() function. The feature introduces a default 'disable' state and uses per-transceiver-type methods to determine LPM status, ensuring accurate reporting across different hardware. Work was implemented in the edge-core/sonic-buildimage repository, with the change recorded in commit 2642babedb223aeaa48d80c6e02008501e246536. This lays groundwork for power management visibility and supports energy-saving decisions across monitored devices. No separate bug fixes were required for this month; the change improves reliability by standardizing LPM status reporting and avoiding ambiguous states.
