LUA-KTX, the GREEN HOUSE GH-USB100B, 46and the Billionton 10/100 FastEthernet USBKR2 "thumb" adaptor. 47.Pp 48The RTL8150 contains an 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.Bl -tag -width ".Cm 10baseT/UTP" 60.It Cm autoselect 61Enable auto selection of the media type and options. 62The user can manually override 63the auto selected mode by adding media options to the 64.Pa /etc/rc.conf 65file. 66.It Cm 10baseT/UTP 67Set 10Mbps operation. 68The 69.Cm mediaopt 70option can also be used to select either 71.Cm full-duplex 72or 73.Cm half-duplex 74modes. 75.It Cm 100baseTX 76Set 100Mbps (Fast Ethernet) operation. 77The 78.Cm mediaopt 79option can also be used to select either 80.Cm full-duplex 81or 82.Cm half-duplex 83modes. 84.El 85.Pp 86The 87.Nm 88driver supports the following media options: 89.Bl -tag -width ".Cm 10baseT/UTP" 90.It Cm full-duplex 91Force full duplex operation. 92.It Cm half-duplex 93Force half duplex operation. 94.El 95.Pp 96For more information on configuring this device, see 97.Xr ifconfig 8 . 98.Sh DIAGNOSTICS 99.Bl -diag 100.It "rue%d: watchdog timeout" 101A packet was queued for transmission and a transmit command was 102issued, however the device failed to acknowledge the transmission 103before a timeout expired. 104.It "rue%d: rx list init failed" 105The driver failed to allocate an mbuf for the transmitter ring. 106.It "rue%d: no memory for rx list" 107The driver failed to allocate an mbuf for the receiver ring. 108.El 109.Sh SEE ALSO 110.Xr arp 4 , 111.Xr miibus 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
