LU-ATX 54.It Tn SMC 2202USB 55.El 56.Sh DESCRIPTION 57The 58.Nm 59driver provides support for USB ethernet adapters based on the ADMtek 60AN986 Pegasus chipset. 61.Pp 62The Pegasus contains a 10/100 63ethernet MAC with MII interface and is designed to work with both 64ethernet and HomePNA transceivers. Although designed to interface with 65100Mbps peripherals, the existing USB standard specifies a maximum 66transfer speed of 12Mbps. Users should therefore not expect to actually 67achieve 100Mbps speeds with these devices. 68.Pp 69The Pegasus supports a 64-bit multicast hash table, single perfect 70filter entry for the station address and promiscuous mode. Packets are 71received and transmitted over separate USB bulk transfer endpoints. 72.Pp 73The 74.Nm 75driver supports the following media types: 76.Pp 77.Bl -tag -width xxxxxxxxxxxxxxxxxxxx 78.It autoselect 79Enable autoselection of the media type and options. 80The user can manually override 81the autoselected mode by adding media options to the 82.Pa /etc/rc.conf 83file. 84.It 10baseT/UTP 85Set 10Mbps operation. The 86.Ar mediaopt 87option can also be used to enable 88.Ar full-duplex 89operation. Not specifying 90.Ar full duplex 91implies 92.Ar half-duplex 93mode. 94.It 100baseTX 95Set 100Mbps (fast ethernet) operation. The 96.Ar mediaopt 97option can also be used to enable 98.Ar full-duplex 99operation. Not specifying 100.Ar full duplex 101implies 102.Ar half-duplex 103mode. 104.El 105.Pp 106The 107.Nm 108driver supports the following media options: 109.Pp 110.Bl -tag -width xxxxxxxxxxxxxxxxxxxx 111.It full-duplex 112Force full duplex operation. The interface will operate in 113half duplex mode if this media option is not specified. 114.El 115.Pp 116For more information on configuring this device, see 117.Xr ifconfig 8 . 118.Sh DIAGNOSTICS 119.Bl -diag 120.It "aue%d: watchdog timeout" 121A packet was queued for transmission and a transmit command was 122issued, however the device failed to acknowledge the transmission 123before a timeout expired. 124.It "aue%d: no memory for rx list" 125The driver failed to allocate an mbuf for the receiver ring. 126.El 127.Sh SEE ALSO 128.Xr arp 4 , 129.Xr ifconfig 8 , 130.Xr netintro 4 , 131.Xr usb 4 132.Rs 133.%T ADMtek AN986 data sheet 134.%O http://www.admtek.com.tw 135.Re 136.Sh HISTORY 137The 138.Nm 139device driver first appeared in 140.Fx 4.0 , 141and in 142.Nx 1.5 . 143.Sh AUTHORS 144The 145.Nm 146driver was written by 147.An Bill Paul Aq wpaul@ee.columbia.edu . 148
