33 .Nd "RealTek RTL8152/RTL8153 USB to Ethernet controller driver"
35 To compile this driver into the kernel,
36 place the following lines in your
37 kernel configuration file:
38 .Bd -ragged -offset indent
47 Alternatively, to load the driver as a
48 module at boot time, place the following line in
50 .Bd -literal -offset indent
56 driver provides support for USB Ethernet adapters based on the RealTek
57 RealTek RTL8152 and RTL8153 USB Ethernet controllers.
59 NICs based on the RTL8152 are capable of 10 and 100Mbps speeds.
60 NICs based on the RTL8153 are capable of 10, 100 and 1000Mbps operation.
64 driver supports the following media types:
65 .Bl -tag -width ".Cm 10baseT/UTP"
67 Enable auto selection of the media type and options.
68 The user can manually override
69 the auto selected mode by adding media options to the
76 option can also be used to select either
82 Set 100Mbps (Fast Ethernet) operation.
85 option can also be used to select either
91 Set 1000baseTX operation over twisted pair.
92 The RealTek gigE chips support 1000Mbps in
99 driver supports the following media options:
100 .Bl -tag -width ".Cm full-duplex"
102 Force full duplex operation.
104 Force half duplex operation.
107 For more information on configuring this device, see
111 .It "ure%d: watchdog timeout"
112 A packet was queued for transmission and a transmit command was
113 issued, however the device failed to acknowledge the transmission
114 before a timeout expired.
