The existing USB 1.0 58 standard specifies a maximum transfer speed of 12Mbps. 59 USB 1.0 Users should therefore not expect to actually achieve 100Mbps speeds 60 with these devices. 61 .Pp 62 The Moschip supports a 64-bit multicast hash table, single perfect 63 filter entry for the station address and promiscuous mode. 64 Packets are 65 received and transmitted over separate USB bulk transfer endpoints. 66 .Pp 67 For more information on configuring this device, see 68 .Xr ifconfig 8 . 69 .Sh HARDWARE 70 Adapters supported by the 71 .Nm 72 driver include: 73 .Pp 74 .Bl -bullet -compact 75 .It 76 Sitecom 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 92 The 93 .Nm 94 device driver first appeared in 95 .Fx 8.2 . 96 .Sh AUTHORS 97 The 98 .Nm 99 driver was written by 100 .An Rick van der Zwet Aq Mt info@rickvanderzwet.nl . 101
