|
|---|
| 23 | .Nd Moschip MCS7730/MCS7840 USB Ethernet driver
|
|---|
| 24 | .Sh SYNOPSIS
|
|---|
| 25 | To compile this driver into the kernel,
|
|---|
| 26 | place the following lines in your
|
|---|
| 27 | kernel configuration file:
|
|---|
| 28 | .Bd -ragged -offset indent
|
|---|
| 29 | .Cd "device uhci"
|
|---|
| 30 | .Cd "device ohci"
|
|---|
| 31 | .Cd "device usb"
|

| 32 | .Cd "device miibus"
|
|---|
| 33 | .Cd "device mos"
|
|---|
| 34 | .Ed
|
|---|
| 35 | .Pp
|
|---|
| 36 | Alternatively, to load the driver as a
|
|---|
| 37 | module at boot time, place the following line in
|
|---|
| 38 | .Xr loader.conf 5 :
|
|---|
| 39 | .Bd -literal -offset indent

| 42 | .Sh DESCRIPTION
|
|---|
| 43 | The
|
|---|
| 44 | .Nm
|
|---|
| 45 | driver provides support for USB Ethernet adapters based on the
|
|---|
| 46 | Moschip MCS7730/MCS7830 chipset.
|
|---|
| 47 | .Pp
|
|---|
| 48 | The adapters that contain the Moschip MCS7730/MCS7830 chipset
|
|---|
| 49 | will operate at 100Base-TX and full-duplex.
|
|---|
| 50 | .Pp
|
|---|
| 51 | The Moschip contains a 10/100
|
|---|
| 52 | Ethernet MAC with MII interface and is designed to work with both
|
|---|
| 53 | Ethernet and HomePNA transceivers.
|
|---|
| 54 | Although designed to interface with
|
|---|
| 55 | 100Mbps peripherals, this only works with USB 2.0. The existing USB 1.0
|
|---|
| 56 | standard specifies a maximum transfer speed of 12Mbps.
|
|---|
| 57 | USB 1.0 Users should therefore not expect to actually achieve 100Mbps speeds
|
|---|
| 58 | with these devices.
|
|---|
| 59 | .Pp
|
|---|
| 60 | The Moschip supports a 64-bit multicast hash table, single perfect
|
|---|
| 61 | filter entry for the station address and promiscuous mode.
|
|---|
| 62 | Packets are
|
|---|
| 63 | received and transmitted over separate USB bulk transfer endpoints.
|
|---|
| 64 | .Pp
