Although designed to interface with 78100Mbps peripherals, the existing USB standard specifies a maximum 79transfer speed of 12Mbps. Users should therefore not expect to actually 80achieve 100Mbps speeds with these devices. 81.Pp 82The Pegasus supports a 64-bit multicast hash table, single perfect 83filter entry for the station address and promiscuous mode. Packets are 84received and transmitted over separate USB bulk transfer endpoints. 85.Pp 86The 87.Nm 88driver supports the following media types: 89.Pp 90.Bl -tag -width xxxxxxxxxxxxxxxxxxxx 91.It autoselect 92Enable automatic selection of the media type and options. The user can 93manually override the automatically selected mode by adding media options to 94the 95.Pa /etc/rc.conf 96file. 97.It 10baseT/UTP 98Set 10Mbps operation. The 99.Ar mediaopt 100option can also be used to enable 101.Ar full-duplex 102operation.

The 111.Ar mediaopt 112option can also be used to enable 113.Ar full-duplex 114operation. Not specifying 115.Ar full duplex 116implies 117.Ar half-duplex 118mode. 119.El 120.Pp 121The 122.Nm 123driver supports the following media options: 124.Pp 125.Bl -tag -width xxxxxxxxxxxxxxxxxxxx 126.It full-duplex 127Force full duplex operation. The interface will operate in half duplex mode 128if this media option is not specified. 129.El 130.Pp 131For more information on configuring this device, see 132.Xr ifconfig 8 . 133.Sh DIAGNOSTICS 134.Bl -diag 135.It "aue%d: watchdog timeout" 136A packet was queued for transmission and a transmit command was 137issued, however the device failed to acknowledge the transmission 138before a timeout expired. 139.It "aue%d: no memory for rx list" 140The driver failed to allocate an mbuf for the receiver ring. 141.El 142.Sh SEE ALSO 143.Xr arp 4 , 144.Xr netintro 4 , 145.Xr usb 4 , 146.Xr ifconfig 8 147.Rs 148.%T ADMtek AN986 data sheet 149.%O http://www.admtek.com.tw 150.Re 151.Sh HISTORY 152The 153.Nm 154device driver first appeared in 155.Fx 4.0 , 156and in 157.Nx 1.5 . 158.Sh AUTHORS 159The 160.Nm 161driver was written by 162.An Bill Paul 163.Aq wpaul@ee.columbia.edu . 164
