PCI Express Fast Ethernet Controller
The JMC260 is a single-chip PCI-Express Fast Ethernet Controller. The Ethernet function is compliant
to IEEE 802.3 Media Access Controller, and IEEE 802.3u 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).
