Ethernet Driver Development

Key Responsibilities:

• Develop, Customize and optimize 

  Ethernet Drivers

   for specific chipsets, board variants.

• Kernel Integration:

   Interface the driver with the

  Linux network stack

  , including the 

  NAPI (New API) subsystem, netdev

  , and 

  sk_buff

  management for efficient packet processing
•  

  Performance Tuning:

   Optimize Ethernet driver performance for 

  high throughput, low latency

  , and minimal CPU utilization. Ensure high scalability and efficient packet handling.
•  

  Debugging & Troubleshooting:

  Investigate, resolve complex network issues related to Ethernet drivers -

  latency problems

  , connectivity issues, and performance degradation.

• System Integration:

   Work closely with HW engineers, firmware developers, kernel team to ensure tight integration between the Ethernet driver and the underlying network stack.
• Leverage tools like 

  Wireshark, tcpdump,

   and 

  kernel logs

  for analysis.
•  

  Platform Support:

   Develop drivers that support multiple platforms, including 

  x86, ARM

  , and other 

  custom SoCs

  (System on Chips)
•  Linux Device driver / Kernel development.
•  

  Design, implement,

   and 

  optimize

  Ethernet drivers for various HW platforms (NICs, switches, and embedded systems
•  Expertise with 

  NICs

  and platform-specific hardware, including 

  PCIe

  and DMA, , and

  Interrupts (MSI/MSI-X)

•  

  Debugging:

   Kernel debugging tools (e.g., GDB, kdb, WinDbg) and network analysis tools.
•  Solid skills in C, Shell scripting, and Compilation environment
•  Good knowledge of Linux Layer 2 / 3 Networking protocols
