Both 83.Cm full-duplex 84and 85.Cm half-duplex 86modes are supported. 87.El 88.Pp 89The 90.Nm 91driver supports the following media options: 92.Bl -tag -width full-duplex 93.It Cm full-duplex 94Force full duplex operation. 95.It Cm half-duplex 96Force half duplex operation. 97.El 98.Pp 99For more information on configuring this device, see 100.Xr ifconfig 8 . 101.Sh DIAGNOSTICS 102.Bl -diag 103.It "lge%d: couldn't map memory" 104A fatal initialization error has occurred. 105.It "lge%d: couldn't map ports" 106A fatal initialization error has occurred. 107.It "lge%d: couldn't map interrupt" 108A fatal initialization error has occurred. 109.It "lge%d: no memory for softc struct!" 110The driver failed to allocate memory for per-device instance information 111during initialization. 112.It "lge%d: failed to enable memory mapping!" 113The driver failed to initialize PCI shared memory mapping. 114This might 115happen if the card is not in a bus-master slot. 116.It "lge%d: no memory for jumbo buffers!" 117The driver failed to allocate memory for jumbo frames during 118initialization. 119.It "lge%d: watchdog timeout" 120The device has stopped responding to the network, or there is a problem with 121the network connection (cable). 122.El 123.Sh SEE ALSO 124.Xr arp 4 , 125.Xr netintro 4 , 126.Xr ng_ether 4 , 127.Xr ifconfig 8 128.Rs 129.%T Level 1 LXT1001 Programming Manual 130.%O http://www.freebsd.org/~wpaul/Level1/LXT1001SRM.pdf 131.Re 132.Sh HISTORY 133The 134.Nm 135device driver first appeared in 136.Fx 5.0 . 137.Sh AUTHORS 138The 139.Nm 140driver was written by 141.An Bill Paul Aq william.paul@windriver.com . 142
