Worked on stabilizing mesh backhaul configuration in the rdkcentral/rdk-wifi-hal repository, focusing on embedded systems and network configuration using C. Addressed a post-firmware release issue where the MTU value on mesh backhaul interfaces mld12 and mld13 would incorrectly revert to 1500, potentially impacting network stability. Implemented a targeted fix to enforce an MTU of 1600 on these interfaces, ensuring consistent network performance across devices. The solution involved explicit MTU configuration logic, directly linked to a traceable commit for maintainability. This work improved mesh backhaul reliability by preventing misconfiguration, demonstrating attention to detail in embedded network environments and firmware integration.
