In theory, of course, you are correct. The network abstractions should
ensure compatibility between any ethernet device driver and any TCP/IP
stack. But in practice, testing can reveal all manner of issues which
no-one was expecting.
We have a port of the lwIP 1.3.1 stack in development and it would
certainly be useful to test new ethernet drivers against this stack.
However, I am _not_ suggesting that the other stacks should now be
neglected.
