The +XMAC provides the gigabit MAC and PHY suspport 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 +.Nm +driver configures dual port SysKonnect adapters such that each XMAC +is treated as a separate logical network interface. Both ports can +operate indepenently of each other and can be connected to separate +networks. The SysKonnect driver software currently only uses the +second port on dual port adapters for failover purposes: if the link +on the primary port fails, the SysKonnect driver will automatically +switch traffic onto the second port. +.Pp +The XaQti XMAC II supports full and half duplex operation with +autonegotiation. The XMAC also supports unlimited frame sizes. +Support for jumbo frames is provided via the interface MTU setting. +Selecting an MTU larger than 1500 bytes with the +.Xr ifconfig 8 +utility configures the adapter to receive and transmit jumbo frames. +Using jumbo frames can greatly improve performance for certain tasks, +such as file transfers and data streaming. +.Pp +The +.Nm +driver supports the following media types: +.Pp +.Bl -tag -width xxxxxxxxxxxxxxxxxxxx +.It autoselect +Enable autoselection of the media type and options. +The user can manually override +the autoselected mode by adding media options to the +.Pa /etc/rc.conf +file. +.It 1000baseSX +Set 1000Mbps (gigabit ethernet) operation.
