31 .Nd "RealTek RTL8152/RTL8153 USB to Ethernet controller driver"
33 To compile this driver into the kernel,
34 place the following lines in your
35 kernel configuration file:
36 .Bd -ragged -offset indent
45 Alternatively, to load the driver as a
46 module at boot time, place the following line in
48 .Bd -literal -offset indent
54 driver provides support for USB Ethernet adapters based on the RealTek
55 RealTek RTL8152 and RTL8153 USB Ethernet controllers.
57 NICs based on the RTL8152 are capable of 10 and 100Mbps speeds.
58 NICs based on the RTL8153 are capable of 10, 100 and 1000Mbps operation.
62 driver supports the following media types:
63 .Bl -tag -width ".Cm 10baseT/UTP"
65 Enable auto selection of the media type and options.
66 The user can manually override
67 the auto selected mode by adding media options to the
74 option can also be used to select either
80 Set 100Mbps (Fast Ethernet) operation.
83 option can also be used to select either
89 Set 1000baseTX operation over twisted pair.
90 The RealTek gigE chips support 1000Mbps in
97 driver supports the following media options:
98 .Bl -tag -width ".Cm full-duplex"
100 Force full duplex operation.
102 Force half duplex operation.
105 For more information on configuring this device, see
109 .It "ure%d: watchdog timeout"
110 A packet was queued for transmission and a transmit command was
111 issued, however the device failed to acknowledge the transmission
112 before a timeout expired.
