The XMAC provides the Gigabit MAC and PHY support while the GEnesis provides an interface to the PCI bus, DMA support, packet buffering and arbitration. The GEnesis can control up to two XMACs simultaneously, allowing dual-port NIC configurations. .Pp The Marvell based adapters are a single integrated circuit, but are still presented as a separate MAC (sk) and controller ASIC (skc). .Pp The GEnesis and Yukon 88E8001, 88E8003 and 88E8010 also support jumbo frames. .Pp The .Nm driver supports the following media types: .Bl -tag -width 1000baseSX .It Cm autoselect Enable autoselection of the media type and options. The user can manually override the autoselected mode by adding media options to the appropriate .Xr hostname.if 5 file. .It Cm 10baseT Set 10Mbps operation. The .Xr ifconfig 8 .Ic mediaopt option can also be used to select either .Cm full-duplex or .Cm half-duplex modes. .It Cm 100baseTX Set 100Mbps (Fast Ethernet) operation. The .Xr ifconfig 8 .Ic mediaopt option can also be used to select either .Cm full-duplex or .Cm half-duplex modes. .It Cm 1000baseT Set 1000baseT (Gigabit Ethernet) operation over twisted pair. Both .Cm full-duplex and .Cm half-duplex modes are supported. .It Cm 1000baseSX Set 1000Mbps (Gigabit Ethernet) operation. Both .Cm full-duplex and .Cm half-duplex modes are supported. .El .Pp The .Nm driver supports the following media options: .Bl -tag -width full-duplex .It Cm full-duplex Force full duplex operation. .It Cm half-duplex Force half duplex operation. .El .Pp For more information on configuring this device, see .Xr ifconfig 8 .
