I use lwip with ecos synthetic target and on my HW with cs8900a. The
only think I had to do by hand is to disable 
CYGPKG_IO_ETH_DRIVERS_STAND_ALONE.
You have 2 eth drivers in ecos - the net and the stand alone (used with
redboot). With lwip you get the third one, it seems to me that your
low level eth driver only supports interrupts when using the standard net
driver (CYGPKG_IO_ETH_DRIVERS_NET) - it may be just a matter of defines.

I would start by changing the
	#ifdef CYGPKG_IO_ETH_DRIVERS_NET
into
	#ifndef CYGPKG_IO_ETH_DRIVERS_STAND_ALONE
in eth_dsr - but it is just a guess since I never used the i82559 driver.

Thanks for that, changed the define in the i82559.c file, configuration now 
builds without errors.

However when I try and use this when making my application (simple test 
application, using makefile supplied with basic1.c, altered to suit), I get 
the following errors.

/******/

Is this anything to do with the 'ioeth.diff' file that I put in the folder 
'packages/io/eth', given in the lwip readme?

Anyone had this problem before or any idea of how to fix this.

Thanks
Stuart.
