The Gigabit (10/100/1000 Mbits/sec) LAN subsystem includes the Marvell Yukon 88E50 and an 
RJ-45 LAN connector with integrated status LEDs.

The Marvell Yukon 88E8050 provides the following functions:
• x1 PCI Express link
• Basic 10/100/1000 Ethernet LAN connectivity
• IEEE 802.1p and 802.1q support
• 10/100/1000 IEEE 802.3 compliant
• Compliant to 802.3x flow control support
• Jumbo frame support
• TCP, IP, UDP checksum offload
• Automatic MDI/MDIX crossover
• Full device driver compatibility
• Configuration EEPROMs that contain the MAC address and ASF 2.0 support
• Wake On LAN technology power management support
• PCI Express Active State Power Management Support (L0s)
• ASF 2.0 support 

Two LEDs are built into the RJ-45 LAN connector (as shown in Figure 12).  Table 6 describes the 
LED states when the board is powered up and the Gigabit LAN subsystem is operating.
