Although designed to interface with 79100Mbps peripherals, the existing USB standard specifies a maximum 80transfer speed of 12Mbps. Users should therefore not expect to actually 81achieve 100Mbps speeds with these devices. 82.Pp 83The Pegasus supports a 64-bit multicast hash table, single perfect 84filter entry for the station address and promiscuous mode. Packets are 85received and transmitted over separate USB bulk transfer endpoints. 86.Pp 87The 88.Nm 89driver supports the following media types: 90.Pp 91.Bl -tag -width xxxxxxxxxxxxxxxxxxxx 92.It autoselect 93Enable automatic selection of the media type and options. The user can 94manually override the automatically selected mode by adding media options to 95the 96.Pa /etc/rc.conf 97file. 98.It 10baseT/UTP 99Set 10Mbps operation. The 100.Ar mediaopt 101option can also be used to enable 102.Ar full-duplex 103operation.

The 112.Ar mediaopt 113option can also be used to enable 114.Ar full-duplex 115operation. Not specifying 116.Ar full duplex 117implies 118.Ar half-duplex 119mode. 120.El 121.Pp 122The 123.Nm 124driver supports the following media options: 125.Pp 126.Bl -tag -width xxxxxxxxxxxxxxxxxxxx 127.It full-duplex 128Force full duplex operation. The interface will operate in half duplex mode 129if this media option is not specified. 130.El 131.Pp 132For more information on configuring this device, see 133.Xr ifconfig 8 . 134.Sh DIAGNOSTICS 135.Bl -diag 136.It "aue%d: watchdog timeout" 137A packet was queued for transmission and a transmit command was 138issued, however the device failed to acknowledge the transmission 139before a timeout expired. 140.It "aue%d: no memory for rx list" 141The driver failed to allocate an mbuf for the receiver ring. 142.El 143.Sh SEE ALSO 144.Xr arp 4 , 145.Xr netintro 4 , 146.Xr usb 4 , 147.Xr ifconfig 8 148.Rs 149.%T ADMtek AN986 data sheet 150.%O http://www.admtek.com.tw 151.Re 152.Sh HISTORY 153The 154.Nm 155device driver first appeared in 156.Fx 4.0 , 157and in 158.Nx 1.5 . 159.Sh AUTHORS 160The 161.Nm 162driver was written by 163.An Bill Paul 164.Aq wpaul@ee.columbia.edu . 165
