LU-ATX, the D-Link DSB-650TX, the 51SMC 2202USB, and those LinkSys USB10T adapters that contain the 52AN986 Pegasus chipset. 53The LinkSys USB10T adapters that contain the AN986 Pegasus chipset 54will operate at 100Base-TX and full-duplex. 55.Pp 56The Pegasus contains a 10/100 57ethernet MAC with MII interface and is designed to work with both 58ethernet and HomePNA transceivers. 59Although designed to interface with 60100Mbps peripherals, the existing USB standard specifies a maximum 61transfer speed of 12Mbps. 62Users should therefore not expect to actually 63achieve 100Mbps speeds with these devices. 64.Pp 65The Pegasus supports a 64-bit multicast hash table, single perfect 66filter entry for the station address and promiscuous mode. 67Packets are 68received and transmitted over separate USB bulk transfer endpoints. 69.Pp 70The 71.Nm 72driver supports the following media types: 73.Pp 74.Bl -tag -width xxxxxxxxxxxxxxxxxxxx 75.It autoselect 76Enable autoselection of the media type and options. 77The user can manually override 78the autoselected mode by adding media options to the 79.Pa /etc/rc.conf 80file. 81.It 10baseT/UTP 82Set 10Mbps operation. 83The 84.Ar mediaopt 85option can also be used to enable 86.Ar full-duplex 87operation. 88Not specifying 89.Ar full duplex 90implies 91.Ar half-duplex 92mode. 93.It 100baseTX 94Set 100Mbps (fast ethernet) operation. 95The 96.Ar mediaopt 97option can also be used to enable 98.Ar full-duplex 99operation. 100Not specifying 101.Ar full duplex 102implies 103.Ar half-duplex 104mode. 105.El 106.Pp 107The 108.Nm 109driver supports the following media options: 110.Pp 111.Bl -tag -width xxxxxxxxxxxxxxxxxxxx 112.It full-duplex 113Force full duplex operation. 114The interface will operate in 115half duplex mode if this media option is not specified. 116.El 117.Pp 118For more information on configuring this device, see 119.Xr ifconfig 8 . 120.Sh DIAGNOSTICS 121.Bl -diag 122.It "aue%d: watchdog timeout" 123A packet was queued for transmission and a transmit command was 124issued, however the device failed to acknowledge the transmission 125before a timeout expired. 126.It "aue%d: no memory for rx list" 127The driver failed to allocate an mbuf for the receiver ring. 128.El 129.Sh SEE ALSO 130.Xr arp 4 , 131.Xr netintro 4 , 132.Xr ng_ether 4 , 133.Xr ifconfig 8 134.Rs 135.%T ADMtek AN986 data sheet 136.%O http://www.admtek.com.tw 137.Re 138.Sh HISTORY 139The 140.Nm 141device driver first appeared in 142.Fx 4.0 . 143.Sh AUTHORS 144The 145.Nm 146driver was written by 147.An Bill Paul Aq wpaul@ee.columbia.edu . 148
