39 .Nd Texas Instruments ThunderLAN ethernet device driver
46 driver provides support for PCI ethernet adapters based on the Texas
47 Instruments ThunderLAN ethernet controller chip.
49 number of Compaq PCI-bus ethernet adapters as well as the integrated
50 ethernet controllers built in to several models of Compaq Prosignia
51 servers and Compaq Deskpro desktop machines.
52 This driver also supports
53 the Olicom OC-2135/2138, OC-2325 and OC-2326 10/100 TX UTP adapters
54 and the Racore 8165 10/100baseTX and 8148 10baseT/100baseTX/100baseFX
55 multi-personality cards.
57 The ThunderLAN controller has a standard MII interface that supports
58 up to 32 physical interface devices (PHYs). It also has a built-in
59 10baseT PHY hardwired at MII address 31, which may be used in some
60 10Mbps-only hardware configurations.
61 In 100Mbps configurations, a
62 National Semiconductor DP83840A or other MII-compliant PHY may be
63 attached to the ThunderLAN's MII bus.
64 If a DP83840A or equivalent
65 is available, the ThunderLAN chip can operate at either 100Mbps or
66 10Mbps in either half-duplex or full-duplex modes.
68 built-in PHY and the DP83840A also support autonegotiation.
72 driver supports the following media types:
73 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
75 Enable autoselection of the media type and options.
77 option is only available on those PHYs that support autonegotiation.
78 Also, the PHY will not advertise those modes that have been explicitly
79 disabled using the following media options.
83 Set 100Mbps (fast ethernet) operation
85 Enable AUI/BNC interface (useful only with the built-in PHY).
90 driver supports the following media options:
91 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
93 Force full duplex operation
95 Force half duplex operation.
97 Enable hardware loopback mode.
100 Note that the 100baseTX media type is only available if supported

107 A fatal initialization error has occurred.
108 .It "tl%d: couldn't map interrupt"
109 A fatal initialization error has occurred.
110 .It "tl%d: device timeout"
111 The device has stopped responding to the network, or there is a problem with
112 the network connection (cable).
113 .It "tl%d: no memory for rx list"
114 The driver failed to allocate an mbuf for the receiver ring.
115 .It "tl%d: no memory for tx list"
116 The driver failed to allocate an mbuf for the transmitter ring when
117 allocating a pad buffer or collapsing an mbuf chain into a cluster.
