The existing USB 1.0 58standard specifies a maximum transfer speed of 12Mbps. 59USB 1.0 Users should therefore not expect to actually achieve 100Mbps speeds 60with these devices. 61.Pp 62The Moschip supports a 64-bit multicast hash table, single perfect 63filter entry for the station address and promiscuous mode. 64Packets are 65received and transmitted over separate USB bulk transfer endpoints. 66.Pp 67For more information on configuring this device, see 68.Xr ifconfig 8 . 69.Sh HARDWARE 70Adapters supported by the 71.Nm 72driver include: 73.Pp 74.Bl -bullet -compact 75.It 76Sitecom LN030 77.El 78.Sh SEE ALSO 79.Xr altq 4 , 80.Xr arp 4 , 81.Xr ifmedia 4 , 82.Xr miibus 4 , 83.Xr netintro 4 , 84.Xr ng_ether 4 , 85.Xr usb 4 , 86.Xr ifconfig 8 87.Rs 88.%T ADMtek AN986 data sheet 89.%U http://www.moschip.com/data/products/MCS7830/Data%20Sheet_7830.pdf 90.Re 91.Sh HISTORY 92The 93.Nm 94device driver first appeared in 95.Fx 8.2 . 96.Sh AUTHORS 97The 98.Nm 99driver was written by 100.An Rick van der Zwet Aq Mt info@rickvanderzwet.nl . 101
