eCos 2.0 is nearly 4 years old - hardly current.

The LXT97x is an ethernet PHY (which is just the physical layer
used by some ethernet chips).  Normally, there is little (or nothing)
required to control these devices - they just do their job.  They do
have a control interface whereby you can set the hardware bit rate,
e.g. 100Mb or 10Mb, detect the presence of a carrier/cable, etc.
They are not [directly] responsible for passing ethernet data, that
job is handled by some other device.

You need to figure out what the actual ethernet device is; depending 
on the platform, this may be a separate device like an 82559 chip, 
etc, or it may be builtin to the CPU (SOC), e.g. on the XScale devices.
