It also has a built-in 5810baseT PHY hardwired at MII address 31, which may be used in some 5910Mbps-only hardware configurations. 60In 100Mbps configurations, a 61National Semiconductor DP83840A or other MII-compliant PHY may be 62attached to the ThunderLAN's MII bus. 63If a DP83840A or equivalent 64is available, the ThunderLAN chip can operate at either 100Mbps or 6510Mbps in either half-duplex or full-duplex modes. 66The ThunderLAN's 67built-in PHY and the DP83840A also support autonegotiation. 68.Pp 69The 70.Nm 71driver supports the following media types: 72.Bl -tag -width xxxxxxxxxxxxxxxxxxxx 73.It autoselect 74Enable autoselection of the media type and options. 75Note that this 76option is only available on those PHYs that support autonegotiation. 77Also, the PHY will not advertise those modes that have been explicitly 78disabled using the following media options. 79.It 10baseT/UTP 80Set 10Mbps operation 81.It 100baseTX 82Set 100Mbps (fast ethernet) operation 83.It 10base5/AUI 84Enable AUI/BNC interface (useful only with the built-in PHY). 85.El 86.Pp 87The 88.Nm 89driver supports the following media options: 90.Bl -tag -width xxxxxxxxxxxxxxxxxxxx 91.It full-duplex 92Force full duplex operation 93.It half-duplex 94Force half duplex operation. 95.It hw-loopback 96Enable hardware loopback mode. 97.El 98.Pp 99Note that the 100baseTX media type is only available if supported 100by the PHY. 101For more information on configuring this device, see 102.Xr ifconfig 8 . 103.Sh DIAGNOSTICS 104.Bl -diag 105.It "tl%d: couldn't map memory" 106A fatal initialization error has occurred. 107.It "tl%d: couldn't map interrupt" 108A fatal initialization error has occurred. 109.It "tl%d: device timeout" 110The device has stopped responding to the network, or there is a problem with 111the network connection (cable). 112.It "tl%d: no memory for rx list" 113The driver failed to allocate an mbuf for the receiver ring. 114.It "tl%d: no memory for tx list" 115The driver failed to allocate an mbuf for the transmitter ring when 116allocating a pad buffer or collapsing an mbuf chain into a cluster. 117.El 118.Sh SEE ALSO 119.Xr arp 4 , 120.Xr ifmedia 4 , 121.Xr miibus 4 , 122.Xr netintro 4 , 123.Xr ng_ether 4 , 124.Xr ifconfig 8 125.Sh HISTORY 126The 127.Nm 128device driver first appeared in 129.Fx 2.2 . 130.Sh AUTHORS 131The 132.Nm 133driver was written by 134.An Bill Paul Aq wpaul@ctr.columbia.edu . 135
