The different models of the supported boards come with some subset of RJ-45, BNC and AUI connectors. Media selection is done using
ifconfig(8) using the standard
ifmedia(4) mechanism. Refer to those manual pages for more information.
The
tl driver doesn't have full automatic media selection. By default it will do an Nway (IEEE 802.3u) negotiation on the 10BASE-T port for the speed and duplex mode with the link partner. If the AUI or BNC port is used, an explicit media type must be specified to
ifconfig(8).
