39 .Nd "Level 1 LXT1001 NetCellerator 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 Level 1 LXT1001
59 NetCellerator Gigabit Ethernet controller chip.
61 The LXT1001 supports fiber PHYs and also a GMII port for use with
62 10/100/1000 copper PHYs, however there are currently no NICs on the
63 market that use this feature.
65 The LXT1001 supports TCP/IP checksum offload for receive and
66 VLAN-based filtering as well as a 64-bit multicast hash filter.
67 It also supports jumbo frames, which can be configured
68 via the interface MTU setting.
69 Selecting an MTU larger than 1500 bytes with the
71 utility configures the adapter to receive and transmit jumbo frames.
72 Using jumbo frames can greatly improve performance for certain tasks,
73 such as file transfers and data streaming.
77 driver supports the following media types:
78 .Bl -tag -width ".Cm 1000baseSX"
80 Enable autoselection of the media type and options.
81 The user can manually override
82 the autoselected mode by adding media options to
85 Set 1000baseSX operation over fiber optic cable.
95 driver supports the following media options:
96 .Bl -tag -width ".Cm full-duplex"
98 Force full duplex operation.
100 Force half duplex operation.
