PROFILE
Mori Fumita
During February 2026, Mfumita developed promiscuous mode support for the NXP Ethernet driver in the Zephyr4Microchip/zephyr repository. Working in Embedded C, Mfumita enhanced the driver to advertise and configure the ETHERNET_PROMISC_MODE capability, ensuring that promiscuous mode remains enabled after initialization and cannot be disabled at runtime. This approach reinforced consistent monitoring behavior for network applications and improved driver robustness, aligning with enterprise telemetry requirements. The work involved careful integration with the Zephyr networking stack and focused on runtime configuration management, resulting in two targeted patches that addressed both feature implementation and a critical bug in mode handling.

2 Commits • 1 Features
Feb 1, 2026February 2026 (Zephyr4Microchip/zephyr): Delivered Promiscuous mode support in the NXP Ethernet driver and reinforced runtime configuration to ensure consistent monitoring behavior. Implemented advertisement of ETHERNET_PROMISC_MODE capability, preserved promiscuous mode after initialization, and added support to configure it via runtime settings. Fixed a critical bug preventing the disabling of promiscuous mode at runtime by returning -EINVAL, aligning behavior with initialization assumptions. These changes enhance network visibility for monitoring apps and improve driver robustness, aligning with the product's focus on reliable telemetry and enterprise workflows. Technologies: Embedded C, Zephyr networking stack, driver capabilities, config management; commit-driven, with changes captured in two patches for the NXP Ethernet driver.
