Rather than add packages like this, use the templates, eg net and
old_net.

Only redboot contains a tcp/ip enabled stub which can be used by
gdb. Your FLOPPY startup application only has a serial port gdb stub.
This is not a problem though, normal TCP/IP will still work and you
just need to use the serial port for gdb.

Also, rather than writing your own test programs, i suggest you first
use the eCos test programs. These are known to work. Enable
CYGPKG_NET_BUILD_HW_TESTS and do a 

make tests

and run the applications in install/tests/net/bsd_tcpip
