39 .Nd "National Semiconductor PCI Gigabit Ethernet adapter driver"
41 To compile this driver into the kernel,
42 place the following lines in your
43 kernel configuration file:
44 .Bd -ragged -offset indent
49 Alternatively, to load the driver as a
50 module at boot time, place the following line in
52 .Bd -literal -offset indent
58 driver provides support for various NICs based on the National Semiconductor
59 DP83820 and DP83821 Gigabit Ethernet controller chips.
61 The DP83820 supports TBI (ten bit interface) and GMII
62 transceivers, which means it can be used with either copper or 1000baseX
64 The DP83820 supports TCP/IP checksum offload and
65 VLAN tagging/insertion as well as a 2048-bit multicast hash filter
66 and up to 4 pattern match buffers.
68 Most cards also use the DP83861 10/100/1000 copper gigabit transceiver
69 chip, which supports autonegotiation of 10, 100 and 1000Mbps modes in
72 The DP83820 also supports jumbo frames, which can be configured
73 via the interface MTU setting.
74 Selecting an MTU larger than 1500 bytes with the
76 utility configures the adapter to receive and transmit jumbo frames.
77 Using jumbo frames can greatly improve performance for certain tasks,
78 such as file transfers and data streaming.
82 driver supports the following media types:
83 .Bl -tag -width 10baseTXUTP
85 Enable autoselection of the media type and options.
86 The user can manually override
87 the autoselected mode by adding media options to
94 option can also be used to select either
100 Set 100Mbps (Fast Ethernet) operation.
104 option can also be used to select either
110 Set 1000baseTX operation over twisted pair.
116 Set 1000Mbps (Gigabit Ethernet) operation.
126 driver supports the following media options:
127 .Bl -tag -width full-duplex
129 Force full duplex operation.
131 Force half duplex operation.
136 driver also supports one special link option for 1000baseTX cards:
137 .Bl -tag -width link0
139 With 1000baseTX cards, establishing a link between two ports requires
140 that one port be configured as a master and the other a slave.
141 With autonegotiation,
142 the master/slave settings will be chosen automatically.
143 However when manually selecting the link state, it is necessary to
144 force one side of the link to be a master and the other a slave.
147 driver configures the ports as slaves by default.
152 will set a port as a master instead.
