LU-ATX 61.It Tn SMC 2202USB 62.El 63.Sh DESCRIPTION 64The 65.Nm 66driver provides support for USB 67.Tn Ethernet 68adapters based on the ADMtek AN986 Pegasus chipset. 69.Pp 70The Pegasus contains a 10/100 71.Tn Ethernet 72MAC with MII interface and is designed to work with both 73.Tn Ethernet 74and HomePNA transceivers. Although designed to interface with 75100Mbps peripherals, the existing USB standard specifies a maximum 76transfer speed of 12Mbps. Users should therefore not expect to actually 77achieve 100Mbps speeds with these devices. 78.Pp 79The Pegasus supports a 64-bit multicast hash table, single perfect 80filter entry for the station address and promiscuous mode. Packets are 81received and transmitted over separate USB bulk transfer endpoints. 82.Pp 83The 84.Nm 85driver supports the following media types: 86.Pp 87.Bl -tag -width xxxxxxxxxxxxxxxxxxxx 88.It autoselect 89Enable automatic selection of the media type and options. The user can 90manually override the automatically selected mode by adding media options to 91the 92.Pa /etc/rc.conf 93file. 94.It 10baseT/UTP 95Set 10Mbps operation. The 96.Ar mediaopt 97option can also be used to enable 98.Ar full-duplex 99operation.

The 108.Ar mediaopt 109option can also be used to enable 110.Ar full-duplex 111operation. Not specifying 112.Ar full duplex 113implies 114.Ar half-duplex 115mode. 116.El 117.Pp 118The 119.Nm 120driver supports the following media options: 121.Pp 122.Bl -tag -width xxxxxxxxxxxxxxxxxxxx 123.It full-duplex 124Force full duplex operation. The interface will operate in half duplex mode 125if this media option is not specified. 126.El 127.Pp 128For more information on configuring this device, see 129.Xr ifconfig 8 . 130.Sh DIAGNOSTICS 131.Bl -diag 132.It "aue%d: watchdog timeout" 133A packet was queued for transmission and a transmit command was 134issued, however the device failed to acknowledge the transmission 135before a timeout expired. 136.It "aue%d: no memory for rx list" 137The driver failed to allocate an mbuf for the receiver ring. 138.El 139.Sh SEE ALSO 140.Xr arp 4 , 141.Xr ifconfig 8 , 142.Xr netintro 4 , 143.Xr usb 4 144.Rs 145.%T ADMtek AN986 data sheet 146.%O http://www.admtek.com.tw 147.Re 148.Sh HISTORY 149The 150.Nm 151device driver first appeared in 152.Fx 4.0 , 153and in 154.Nx 1.5 . 155.Sh AUTHORS 156The 157.Nm 158driver was written by Bill Paul 159.Aq wpaul@ee.columbia.edu . 160
