Supported media include: 60.Pp 61.Bl -tag -width xxxxxxxxxx -offset indent 62.It AUI/DIX 63Standard 15 pin connector 64.It 10Base2 65BNC, also known as thin-net 66.It 10BaseT 67UTP, also known as twisted pair 68.It 100baseTX 69100Mbit over cat-5 UTP 70.El 71.Pp 72The 73.Nm 74driver don't have automatic media selection, and there is no media selected 75by default. An explicit medium must be specified to 76.Xr ifconfig 8 77or in your /etc/ifconfig.tl? file. The media option 78.Em full-duplex 79can be used to switch the UTP port in full-duplex mode. 80.Sh DIAGNOSTICS 81.Dl "tl0: no carrier" 82.Dl "nsphy0: 10baseT: no carrier" 83.in +4 84means that the driver detected a carrier loss. This usually indicates a bad 85link. 86.in -4 87.Sh BUGS 88The board marked as untested will always claim having an AUI connector, where 89it may be a BNC one. 90.Pp 91The driver really should have a media autosensing function. 92.Pp 93On AUI and BNC ports, false carrier loss may be detected on heavily-loaded 94networks. 95.Sh SEE ALSO 96.Xr ifconfig 8 , 97.Xr intro 4 , 98.Xr pci 4 99
