>The network drivers use a two-layer design.  One layer is
hardware independent and contains all the stack specific code.
The other layer is platform dependent and communicates with the
hardware independent layer via a very simple API.  In this way,
hardware device drivers can actually be used with other stacks,
if the same API can be provided by that stack.  We designed the
drivers this way to encourage the development of other stacks in
eCos while allowing re-use of the actual hardware specific code. </P
