The application. They should be default disabled anyway.

And if you build an application without this package (or the TCP/IP stack)
do breakpoints now work?

Can you try the old redboot, but _enabling_ stubs in your application i.e.
CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS

Even if there was some sort of incompatibility between your hardware and
the eth driver, I wouldn't expect it to affect breakpoints.
