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