LU-ATX, the D-Link DSB-650TX and the 52SMC 2202USB. 53.Pp 54The Pegasus contains a 10/100 55ethernet MAC with MII interface and is designed to work with both 56ethernet and HomePNA transceivers. Although designed to interface with 57100Mbps peripherals, the existing USB standard specifies a maximum 58transfer speed of 12Mbps. Users should therefore not expect to actually 59achieve 100Mbps speeds with these devices. 60.Pp 61The Pegasus supports a 64-bit multicast hash table, single perfect 62filter entry for the station address and promiscuous mode. Packets are 63received and transmitted over separate USB bulk transfer endpoints. 64.Pp 65The 66.Nm 67driver supports the following media types: 68.Pp 69.Bl -tag -width xxxxxxxxxxxxxxxxxxxx 70.It autoselect 71Enable autoselection of the media type and options. 72The user can manually override 73the autoselected mode by adding media options to the 74.Pa /etc/rc.conf 75file. 76.It 10baseT/UTP 77Set 10Mbps operation. The 78.Ar mediaopt 79option can also be used to enable 80.Ar full-duplex 81operation. Not specifying 82.Ar full duplex 83implies 84.Ar half-duplex 85mode. 86.It 100baseTX 87Set 100Mbps (fast ethernet) operation. The 88.Ar mediaopt 89option can also be used to enable 90.Ar full-duplex 91operation. Not specifying 92.Ar full duplex 93implies 94.Ar half-duplex 95mode. 96.El 97.Pp 98The 99.Nm 100driver supports the following media options: 101.Pp 102.Bl -tag -width xxxxxxxxxxxxxxxxxxxx 103.It full-duplex 104Force full duplex operation. The interface will operate in 105half duplex mode if this media option is not specified. 106.El 107.Pp 108For more information on configuring this device, see 109.Xr ifconfig 8 . 110.Sh DIAGNOSTICS 111.Bl -diag 112.It "aue%d: watchdog timeout" 113A packet was queued for transmission and a transmit command was 114issued, however the device failed to acknowledge the transmission 115before a timeout expired. 116.It "aue%d: no memory for rx list" 117The driver failed to allocate an mbuf for the receiver ring. 118.El 119.Sh SEE ALSO 120.Xr arp 4 , 121.Xr netintro 4 , 122.Xr ifconfig 8 , 123.Xr ng_ether 8 124.Rs 125.%T ADMtek AN986 data sheet 126.%O http://www.admtek.com.tw 127.Re 128.Sh HISTORY 129The 130.Nm 131device driver first appeared in 132.Fx 4.0 . 133.Sh AUTHORS 134The 135.Nm 136driver was written by 137.An Bill Paul Aq wpaul@ee.columbia.edu . 138
