40 .Nd "Level 1 LXT1001 NetCellerator PCI gigabit ethernet adapter driver"
47 driver provides support for various NICs based on the Level 1 LXT1001
48 NetCellerator gigabit ethernet controller chip, including the
53 SMC TigerCard 1000 (SMC9462SX)
58 These NICs are capable of 1000mbps speeds over fiber optic cable.
59 The LXT1001 also supports a GMII port for use with 10/100/1000 copper
60 PHYs, however there aren't currently any NICs on the market that use
63 The LXT1001 supports TCP/IP checksum offload for receive and
64 VLAN-based filtering as well as a 64-bit multicast hash filter.
65 It also supports jumbo frames, which can be configured
66 via the interface MTU setting.
67 Selecting an MTU larger than 1500 bytes with the
69 utility configures the adapter to receive and transmit jumbo frames.
70 Using jumbo frames can greatly improve performance for certain tasks,
71 such as file transfers and data streaming.
75 driver supports the following media types:
76 .Bl -tag -width ".Cm 1000baseSX"
78 Enable autoselection of the media type and options.
79 The user can manually override
80 the autoselected mode by adding media options to
83 Set 1000baseSX operation over fiber optic cable.
93 driver supports the following media options:
94 .Bl -tag -width ".Cm full-duplex"
96 Force full duplex operation.
98 Force half duplex operation.
