Look at the following msg thread:

Ahh, thanks, msg00003.html contained the solution (at least for me).
I changed:

#ifdef CYGPKG_IO_ETH_DRIVERS_NET

to:

#ifndef CYGPKG_IO_ETH_DRIVERS_STAND_ALONE

in packages/devs/eth/intel/i82559/current/src/if_i82559.c

Now at least the tree compiles cleanly, so it's a big step in the right
direction.
