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.
