Worked on Linux kernel driver and networking enhancements, delivering three features across the geerlingguy/linux and torvalds/linux repositories. Focused on improving FBNIC driver reliability by addressing deadlock risks during power management resume and refactoring interface initialization for better concurrency control. Enhanced BMC connectivity and multicast routing by updating promiscuous mode handling and synchronizing MAC address management between firmware and kernel, supporting robust packet routing. Refactored internal APIs to use fbnic_dev pointers, streamlining code maintainability. All work was implemented in C, leveraging expertise in Linux kernel development, driver development, and network programming to reduce runtime risk and improve hardware compatibility.
