In linux kernel since version 5.15.218 (release Date: 2026-08-27)
Driver for the microcontroller (MCU) that fronts the PSE
hardware on various Realtek-based managed switches, attached
via I2C/SMBus. The MCU exposes a message-based protocol; the actual
PSE silicon is not accessed directly. To compile this driver as a
module, choose M here: the module will be called realtek-pse-mcu-i2c.
