40.Sh SYNOPSIS
|
| 41To compile support for the
42.Nm
43driver into your kernel, place the following lines in your kernel configuration file:
44.Bd -ragged -offset indent
|
41.Cd "device miibus"
42.Cd "device nge"
| 45.Cd "device miibus"
46.Cd "device nge"

49Alternatively, to load the
50.Nm
51driver at boot time, place the following line in
52.Xr loader.conf 5 :
53.Bd -literal -offset indent
54if_nge_load="YES"
55.Ed
|
43.Sh DESCRIPTION
44The
45.Nm
46driver provides support for various NICs based on the National Semiconductor
47DP83820 and DP83821 Gigabit Ethernet controller chips.
48.Pp
49The DP83820 supports TBI (ten bit interface) and GMII
50transceivers, which means it can be used with either copper or 1000baseX
51fiber applications.
52The DP83820 supports TCP/IP checksum offload and
53VLAN tagging/insertion as well as a 2048-bit multicast hash filter
54and up to 4 pattern match buffers.
55.Pp
56Most cards also use the DP83861 10/100/1000 copper gigabit transceiver
57chip, which supports autonegotiation of 10, 100 and 1000Mbps modes in
58full or half duplex.
59.Pp
60The DP83820 also supports jumbo frames, which can be configured
61via the interface MTU setting.
62Selecting an MTU larger than 1500 bytes with the
63.Xr ifconfig 8
64utility configures the adapter to receive and transmit jumbo frames.
65Using jumbo frames can greatly improve performance for certain tasks,
66such as file transfers and data streaming.
67.Pp
68The
69.Nm
70driver supports the following media types:
71.Bl -tag -width 10baseTXUTP
72.It Cm autoselect
73Enable autoselection of the media type and options.
74The user can manually override
75the autoselected mode by adding media options to
76.Xr rc.conf 5 .
77.It Cm 10baseT/UTP
78Set 10Mbps operation.
79The
80.Xr ifconfig 8
81.Ic mediaopt
82option can also be used to select either
83.Cm full-duplex
84or
85.Cm half-duplex
86modes.
87.It Cm 100baseTX
88Set 100Mbps (Fast Ethernet) operation.
89The
90.Xr ifconfig 8
91.Ic mediaopt
92option can also be used to select either
93.Cm full-duplex
94or
95.Cm half-duplex
96modes.
97.It Cm 1000baseTX
98Set 1000baseTX operation over twisted pair.
99.Cm full-duplex
100and
101.Cm half-duplex
102modes are supported.
103.It Cm 1000baseSX
104Set 1000Mbps (Gigabit Ethernet) operation.
105Both
106.Cm full-duplex
107and
108.Cm half-duplex
109modes are supported.
110.El
111.Pp
112The
113.Nm
114driver supports the following media options:
115.Bl -tag -width full-duplex
116.It Cm full-duplex
117Force full duplex operation.
118.It Cm half-duplex
119Force half duplex operation.
120.El
121.Pp
122The
123.Nm
124driver also supports one special link option for 1000baseTX cards:
125.Bl -tag -width link0
126.It Cm link0
127With 1000baseTX cards, establishing a link between two ports requires
128that one port be configured as a master and the other a slave.
129With autonegotiation,
130the master/slave settings will be chosen automatically.
131However when manually selecting the link state, it is necessary to
132force one side of the link to be a master and the other a slave.
133The
134.Nm
135driver configures the ports as slaves by default.
136Setting the
137.Cm link0
138flag with
139.Xr ifconfig 8
140will set a port as a master instead.
141.El

144.Xr ifconfig 8 .
