The existing USB 1.0 57standard specifies a maximum transfer speed of 12Mbps. 58USB 1.0 Users should therefore not expect to actually achieve 100Mbps speeds 59with these devices. 60.Pp 61The Moschip supports a 64-bit multicast hash table, single perfect 62filter entry for the station address and promiscuous mode. 63Packets are 64received and transmitted over separate USB bulk transfer endpoints. 65.Pp 66For more information on configuring this device, see 67.Xr ifconfig 8 . 68.Sh HARDWARE 69Adapters supported by the 70.Nm 71driver include: 72.Pp 73.Bl -bullet -compact 74.It 75Sitecom LN030 76.El 77.Sh SEE ALSO 78.Xr altq 4 , 79.Xr arp 4 , 80.Xr ifmedia 4 , 81.Xr miibus 4 , 82.Xr netintro 4 , 83.Xr ng_ether 4 , 84.Xr ifconfig 8 85.Rs 86.%T ADMtek AN986 data sheet 87.%O http://www.moschip.com/data/products/MCS7830/Data%20Sheet_7830.pdf 88.Re 89.Sh HISTORY 90The 91.Nm 92device driver first appeared in 93.Fx 8.2 . 94.Sh AUTHORS 95The 96.Nm 97driver was written by 98.An Rick van der Zwet Aq Mt info@rickvanderzwet.nl . 99
