This article provides an overview of the JMicron JMC25x/JMC26x Ethernet Controller and its associated driver, version 0.0.33.3. It delves into the controller’s capabilities, its compliance with industry standards, and key features designed to enhance network performance and efficiency. This driver enables the functionality of the JMicron JMC25x/JMC26x Ethernet Controller.

The JMC25x/JMC26x is a single-chip PCI-Express Gigabit Ethernet Controller. The Ethernet function is compliant to IEEE 802.3 Media Access Controller, and IEEE 802.3u 1000BASE-T/100BASE-TX/ 10BASE-T. The MAC supports IPV4, IPV6, TCP, UDP checksum, segmentation task-offload, priority encoding and IEEE802.1Q VLAN features. It also supports Receive Side Scaling (RSS) to balance the loading for multiple CPUs. The Ethernet function supports remote wakeup (including AMD Magic Packet? and Microsoft? Wake-up frame) in both ACPI and APM (Advanced Power Management).

Understanding the JMicron JMC25x/JMC26x Ethernet Controller

The JMicron JMC25x and JMC26x are single-chip PCI-Express Gigabit Ethernet Controllers designed to provide high-speed network connectivity. These controllers are integral components in systems requiring reliable and efficient Ethernet communication. They are designed to be versatile and compatible with a range of network environments.

Compliance with Industry Standards:

A crucial aspect of the JMC25x/JMC26x controllers is their adherence to established Ethernet standards. The Ethernet function of these controllers is compliant with the following IEEE specifications:

  • IEEE 802.3 Media Access Controller (MAC): This standard defines the rules governing how devices access and transmit data on a shared network medium.
  • IEEE 802.3u 1000BASE-T/100BASE-TX/10BASE-T: These standards specify the physical layer requirements for Gigabit Ethernet (1000BASE-T), Fast Ethernet (100BASE-TX), and standard Ethernet (10BASE-T) over twisted-pair cabling. This ensures compatibility with a wide range of network infrastructures.

Key Features and Functionality:

The JMicron JMC25x/JMC26x Ethernet Controller boasts a range of features aimed at optimizing network performance and resource utilization. These features are typically implemented within the Media Access Controller (MAC) layer of the controller:

  • IPv4 and IPv6 Support: The controller supports both Internet Protocol versions 4 and 6, ensuring compatibility with current and future network addressing schemes.
  • TCP and UDP Checksum Offload: This feature offloads the calculation of TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) checksums from the CPU to the Ethernet controller. This reduces the CPU’s workload, freeing up resources for other tasks and improving overall system performance.
  • Segmentation Task Offload: Large data packets are often segmented into smaller units for transmission across a network. The segmentation task offload feature allows the Ethernet controller to handle this segmentation process, again reducing the burden on the CPU.
  • Priority Encoding: This feature allows for the prioritization of network traffic based on its importance. This is crucial for ensuring that time-sensitive data, such as voice or video, is transmitted with minimal delay.
  • IEEE 802.1Q VLAN (Virtual LAN) Features: VLANs allow for the logical segmentation of a network into smaller, more manageable broadcast domains. The JMC25x/JMC26x controller supports VLAN tagging, enabling the creation and management of VLANs.
  • Receive Side Scaling (RSS): RSS is a technology that distributes network processing load across multiple CPU cores in a multi-processor system. By distributing the workload, RSS can significantly improve network throughput and reduce latency, especially in high-traffic environments. This feature is particularly beneficial for server applications and other systems that require high network performance.
  • Remote Wakeup: The Ethernet function of the JMC25x/JMC26x supports remote wakeup functionality, allowing a system to be powered on remotely via a network signal. This includes support for both AMD Magic Packet? and Microsoft? Wake-up frame standards. This feature is compatible with both ACPI (Advanced Configuration and Power Interface) and APM (Advanced Power Management) power management schemes.
