47 .Bd -literal -offset indent
53 driver provides support for SysKonnect based Gigabit Ethernet adapters and
54 Marvell based Gigabit Ethernet adapters.
56 The SysKonnect based adapters consist of two main components:
57 the XaQti Corp. XMAC II gigabit MAC and
58 the SysKonnect GEnesis controller ASIC.
59 The XMAC provides the gigabit MAC and PHY support
60 while the GEnesis provides an interface to the PCI bus,
61 DMA support, packet buffering and arbitration.
62 The GEnesis can control up to two XMACs simultaneously,
63 allowing dual-port NIC configurations.
65 The Marvell based adapters are a single integrated circuit,
66 but are still presented as a separate MAC and controller ASIC.
70 driver configures dual port SysKonnect adapters such that each XMAC
71 is treated as a separate logical network interface.
73 operate independently of each other and can be connected to separate
75 The SysKonnect driver software currently only uses the
76 second port on dual port adapters for failover purposes: if the link
77 on the primary port fails, the SysKonnect driver will automatically
78 switch traffic onto the second port.
80 The XaQti XMAC II supports full and half duplex operation with
82 The XMAC also supports unlimited frame sizes.
83 Support for jumbo frames is provided via the interface MTU setting.
84 Selecting an MTU larger than 1500 bytes with the
86 utility configures the adapter to receive and transmit jumbo frames.
87 Using jumbo frames can greatly improve performance for certain tasks,
88 such as file transfers and data streaming.
92 driver supports the following media types:
93 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
95 Enable autoselection of the media type and options.
96 The user can manually override
97 the autoselected mode by adding media options to the
101 Set 1000baseT operation over twisted pair.
102 This is only available
103 for SK-982x series adapters with 1000baseT ports.
110 Set 1000Mbps (gigabit ethernet) operation.
120 driver supports the following media options:
121 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
123 Force full duplex operation
125 Force half duplex operation.
130 driver also supports one special link option for 1000baseT cards:
131 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
133 With 1000baseT cards, establishing a link between two ports requires
134 that one port be configured as a master and the other a slave.
135 With autonegotiation,
136 the master/slave settings will be chosen automatically.
137 However when manually selecting the link state, it is necessary to
138 force one side of the link to be a master and the other a slave.
141 driver configures the ports as slaves by default.
146 will set a port as a master instead.
