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.Bl -tag -width xxxxxxxxxxxxxxxxxxxx 74.It autoselect 75Enable autoselection of the media type and options. 76The user can manually override 77the autoselected mode by adding media options to the 78.Pa /etc/rc.conf 79file. 80.It 10baseT/UTP 81Set 10Mbps operation. 82The 83.Ar mediaopt 84option can also be used to enable 85.Ar full-duplex 86operation. 87Not specifying 88.Ar full duplex 89implies 90.Ar half-duplex 91mode. 92.It 100baseTX 93Set 100Mbps (fast ethernet) operation. 94The 95.Ar mediaopt 96option can also be used to enable 97.Ar full-duplex 98operation. 99Not 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.Bl -tag -width xxxxxxxxxxxxxxxxxxxx 110.It full-duplex 111Force full duplex operation. 112The 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 ifmedia 4 , 130.Xr miibus 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 Mt wpaul@ee.columbia.edu . 148
