35 To compile this driver into the kernel,
36 place the following lines in your
37 kernel configuration file:
38 .Bd -ragged -offset indent
46 Alternatively, to load the driver as a
47 module at boot time, place the following line in
49 .Bd -literal -offset indent
55 driver provides support for USB Ethernet adapters based on the RealTek
56 RTL8150 USB to Fast Ethernet controller chip.
58 The RTL8150 contains an integrated Fast Ethernet MAC, which supports
59 both 10 and 100Mbps speeds in either full or half duplex.
60 Although designed to interface with
61 100Mbps peripheral, the existing USB standard specifies a maximum
62 transfer speed of 12Mbps.
63 Users should therefore not expect to actually
64 achieve 100Mbps speeds with this device.
68 driver supports the following media types:
69 .Bl -tag -width ".Cm 10baseT/UTP"
71 Enable auto selection of the media type and options.
72 The user can manually override
73 the auto selected mode by adding media options to the
80 option can also be used to select either
86 Set 100Mbps (Fast Ethernet) operation.
89 option can also be used to select either
98 driver supports the following media options:
99 .Bl -tag -width ".Cm 10baseT/UTP"
101 Force full duplex operation.
103 Force half duplex operation.
