LUA-KTX and the GREEN HOUSE GH-USB100B. 47.Pp 48The RTL8150 contains a integrated Fast Ethernet MAC, which supports 49both 10 and 100Mbps speeds in either full or half duplex. 50Although designed to interface with 51100Mbps peripheral, the existing USB standard specifies a maximum 52transfer speed of 12Mbps. 53Users should therefore not expect to actually 54achieve 100Mbps speeds with this device. 55.Pp 56The 57.Nm 58driver supports the following media types: 59.Pp 60.Bl -tag -width xxxxxxxxxxxxxxxx 61.It autoselect 62Enable auto selection of the media type and options. 63The user can manually override 64the auto selected mode by adding media options to the 65.Pa /etc/rc.conf 66file. 67.It 10baseT/UTP 68Set 10Mbps operation. 69The 70.Ar mediaopt 71option can also be used to select either 72.Ar full-duplex 73or 74.Ar half-duplex 75modes. 76.It 100baseTX 77Set 100Mbps (Fast Ethernet) operation. 78The 79.Ar mediaopt 80option can also be used to select either 81.Ar full-duplex 82or 83.Ar half-duplex 84modes. 85.El 86.Pp 87The 88.Nm 89driver supports the following media options: 90.Pp 91.Bl -tag -width xxxxxxxxxxxxxxxx 92.It full-duplex 93Force full duplex operation. 94.It half-duplex 95Force half duplex operation. 96.El 97.Pp 98For more information on configuring this device, see 99.Xr ifconfig 8 . 100.Sh DIAGNOSTICS 101.Bl -diag 102.It "rue%d: watchdog timeout" 103A packet was queued for transmission and a transmit command was 104issued, however the device failed to acknowledge the transmission 105before a timeout expired. 106.It "rue%d: rx list init failed" 107The driver failed to allocate an mbuf for the transmitter ring. 108.It "rue%d: no memory for rx list" 109The driver failed to allocate an mbuf for the receiver ring. 110.Sh SEE ALSO 111.Xr arp 4 , 112.Xr netintro 4 , 113.Xr ng_ether 4 , 114.Xr ifconfig 8 115.Rs 116.%T ReakTek RTL8150 data sheet 117.%O ftp://ftp.realtek.com.tw/lancard/data_sheet/8150/ 118.Re 119.Sh HISTORY 120The 121.Nm 122device driver first appeared in 123.Fx 5.1 . 124.Sh AUTHORS 125The 126.Nm 127driver was written by 128.An Shunsuke Akiyama Aq akiyama@FreeBSD.org . 129
