Although designed to interface with 77100Mbps peripherals, the existing USB standard specifies a maximum 78transfer speed of 12Mbps. Users should therefore not expect to actually 79achieve 100Mbps speeds with these devices. 80.Pp 81The Pegasus supports a 64-bit multicast hash table, single perfect 82filter entry for the station address and promiscuous mode. Packets are 83received and transmitted over separate USB bulk transfer endpoints. 84.Pp 85The 86.Nm 87driver supports the following media types: 88.Pp 89.Bl -tag -width xxxxxxxxxxxxxxxxxxxx 90.It autoselect 91Enable automatic selection of the media type and options. The user can 92manually override the automatically selected mode by adding media options to 93the 94.Pa /etc/rc.conf 95file. 96.It 10baseT/UTP 97Set 10Mbps operation. The 98.Ar mediaopt 99option can also be used to enable 100.Ar full-duplex 101operation.

The 110.Ar mediaopt 111option can also be used to enable 112.Ar full-duplex 113operation. Not specifying 114.Ar full duplex 115implies 116.Ar half-duplex 117mode. 118.El 119.Pp 120The 121.Nm 122driver supports the following media options: 123.Pp 124.Bl -tag -width xxxxxxxxxxxxxxxxxxxx 125.It full-duplex 126Force full duplex operation. The interface will operate in half duplex mode 127if this media option is not specified. 128.El 129.Pp 130For more information on configuring this device, see 131.Xr ifconfig 8 . 132.Sh DIAGNOSTICS 133.Bl -diag 134.It "aue%d: watchdog timeout" 135A packet was queued for transmission and a transmit command was 136issued, however the device failed to acknowledge the transmission 137before a timeout expired. 138.It "aue%d: no memory for rx list" 139The driver failed to allocate an mbuf for the receiver ring. 140.El 141.Sh SEE ALSO 142.Xr arp 4 , 143.Xr netintro 4 , 144.Xr usb 4 , 145.Xr ifconfig 8 146.Rs 147.%T ADMtek AN986 data sheet 148.%O http://www.admtek.com.tw 149.Re 150.Sh HISTORY 151The 152.Nm 153device driver first appeared in 154.Fx 4.0 , 155and in 156.Nx 1.5 . 157.Sh AUTHORS 158The 159.Nm 160driver was written by 161.An Bill Paul 162.Aq wpaul@ee.columbia.edu . 163
