I have fixed my PC for 100mbps & Full Duplex.

I checked changing ethernet cable and PC.

When I connect to hub and auto-negotiation is enable 100mbps & Full duplex connection is established. But when I connect my custom board directly to PC via cross ethernet cable, 100mbps & Half duplex is established.

I wish to have 100mbps & Full duplex connection establishment for my project.

I am using Triple-speed Ethernet MAC, Marvell 88E1111 Phy on my custom board.
