The existing USB 1.0 +standard specifies a maximum transfer speed of 12Mbps. +USB 1.0 Users should therefore not expect to actually achieve 100Mbps speeds +with these devices. +.Pp +The Moschip supports a 64-bit multicast hash table, single perfect +filter entry for the station address and promiscuous mode. +Packets are +received and transmitted over separate USB bulk transfer endpoints. +.Pp +For more information on configuring this device, see +.Xr ifconfig 8 . +.Sh HARDWARE +Adapters supported by the +.Nm +driver include: +.Pp +.Bl -bullet -compact +.It +Sitecom LN030 +.Sh SEE ALSO +.Xr altq 4 , +.Xr arp 4 , +.Xr miibus 4 , +.Xr netintro 4 , +.Xr ng_ether 4 , +.Xr ifconfig 8 +.Rs +.%T ADMtek AN986 data sheet +.%O http://www.moschip.com/data/products/MCS7830/Data%20Sheet_7830.pdf +.Re +.Sh HISTORY +The +.Nm +device driver first appeared in +.Fx 8.2 . +.Sh AUTHORS +The +.Nm +driver was written by +.An Rick van der Zwet [email protected] .
