PCI Express Gigabit Ethernet Controller
The JMC250 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).
