39 .Nd "Intel(R) PRO/1000 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
48 Alternatively, to load the driver as a
49 module at boot time, place the following line in
51 .Bd -literal -offset indent
57 driver provides support for PCI Gigabit Ethernet adapters based on
58 the Intel 82540, 82541ER, 82541PI, 82542, 82543, 82544, 82545, 82546,
59 82546EB, 82546GB, 82547 and 82573 Ethernet controller chips.
60 The driver supports Transmit/Receive checksum offload
61 and Jumbo Frames only on 82540, 82543, 82544 and 82546-based adapters.
62 For further hardware information, see the
64 included with the driver.
66 For questions related to hardware requirements,
67 refer to the documentation supplied with your Intel PRO/1000 adapter.
68 All hardware requirements listed apply to use with
71 Support for Jumbo Frames is provided via the interface MTU setting.
72 Selecting an MTU larger than 1500 bytes with the
74 utility configures the adapter to receive and transmit Jumbo Frames.
75 The maximum MTU size for Jumbo Frames is 16114.
77 This driver version supports VLANs.
78 For information on enabling VLANs, see the
82 driver supports the following media types:
83 .Bl -tag -width ".Cm 10baseT/UTP"
85 Enables auto-negotiation for speed and duplex.
87 Sets 10Mbps operation.
94 Sets 100Mbps operation.
101 Sets 1000Mbps operation.
104 mode is supported at this speed.
106 Sets 1000Mbps operation.
109 mode is supported at this speed.
114 driver supports the following media options:
115 .Bl -tag -width ".Cm full-duplex"
117 Forces full-duplex operation
119 Forces half-duplex operation.
128 is not specified, the driver defaults to
