43 driver provides support for USB Ethernet adapters based on the RealTek
44 RTL8150 USB to Fast Ethernet controller chip.
45 This includes the Melco Inc. LUA-KTX, the GREEN HOUSE GH-USB100B,
46 and the Billionton 10/100 FastEthernet USBKR2 "thumb" adaptor.
48 The RTL8150 contains an integrated Fast Ethernet MAC, which supports
49 both 10 and 100Mbps speeds in either full or half duplex.
50 Although designed to interface with
51 100Mbps peripheral, the existing USB standard specifies a maximum
52 transfer speed of 12Mbps.
53 Users should therefore not expect to actually
54 achieve 100Mbps speeds with this device.
58 driver supports the following media types:
59 .Bl -tag -width ".Cm 10baseT/UTP"
61 Enable auto selection of the media type and options.
62 The user can manually override
63 the auto selected mode by adding media options to the
70 option can also be used to select either
76 Set 100Mbps (Fast Ethernet) operation.
79 option can also be used to select either
88 driver supports the following media options:
89 .Bl -tag -width ".Cm 10baseT/UTP"
91 Force full duplex operation.
93 Force half duplex operation.

100 .It "rue%d: watchdog timeout"
101 A packet was queued for transmission and a transmit command was
102 issued, however the device failed to acknowledge the transmission
103 before a timeout expired.
104 .It "rue%d: rx list init failed"
105 The driver failed to allocate an mbuf for the transmitter ring.
