These are often known 36by their part numbers, most often 3c905 or 3c900 variants. 37.Lp 38The 3c905 devices generally support some form of 100 Mbps Ethernet, 39whereas the 3c900 devices usually only support 10 Mbps. Some devices 40support legacy media such as 10BASE-15, 10BASE-2, and even 10BASE-FL. 41. 42Where applicable, the devices support auto-negotiation, both full and 43half duplex, etc. They also support full size MTUs (1500 bytes), 44even when used with VLANs. 45. 46.Lp 47The device driver supports the 48.Xr ieee802.3 5 49properties, which can be configured with 50.Xr dladm 1M . 51.Lp 52In addition, for devices with multiple external media ports, the driver 53supports a driver-specific 54.Xr dladm 1M 55property called 56.Sy media , 57which can take one of the following values, depending on the available 58media options on the device: 59.Lp 60.Bl -tag -compact -offset indent -width Sy 61.It Sy mii 62Media Indendent Interface (MII), also 100BASE-TX 63.It Sy tp-hdx 6410 Mbps twisted pair, half-duplex 65.It Sy tp-fdx 6610 Mbps twisted pair full-duplex 67.It Sy fx-hdx 68100BASE-FX (fiber), half-duplex 69.It Sy fx-hdx 70100BASE-FX (fiber), full-duplex 71.It Sy bnc 7210BASE-2 73.Pq BNC, aka Dq thin-net 74.It Sy aui 7510BASE-15 76.Pq aka Dq thick-net 77.It Sy fl-hdx 7810BASE-FL (fiber), half-duplex 79.It Sy fl-fdx 8010BASE-FL (fiber), full-duplex 81.El 82.Lp 83The specific media options available can be queried with the 84device-specific 85.Sy available_media 86.Xr dladm 1M 87property. 88.Sh FILES 89.Bl -tag -width /dev/elxl 90.It Pa /dev/elxl 91Special character device. 92.El 93.Sh SEE ALSO 94.Xr dladm 1M , 95.Xr ifconfig 1M , 96.Xr pci 4 , 97.Xr ieee802.3 5 , 98.Xr dlpi 7P 99.Rs 100.%T IEEE 802.3: Ethernet 101.%Q IEEE Standards Association 102.Re 103
