3.6.6 External Transceivers

Some external transceivers support multiple link capabilities, such as
100BASE-T4, 100BASE-TX, and 10BASE-T, but not auto-negotiation. In this
case, the driver attempts to bring-up the link in the highest priority capability
in the following descending order of priority:

100BASE-T4

100BASE-TX

10BASE-T

To bring-up your external transceiver in a lower priority capability, you must
configure the driver parameters to force the link to the desired mode.

Refer to your external transceiver documentation or the Platform Notes: The hme
Fast Ethernet Device Driver
document (Part No: 802-5333) for more information
on forcing the link mode.

Note – When using an external transceiver with the SunFastEthernet Adapter,
your system may not report the speed at which the link is operating, either 10
or 100 Mbps.
