commit <47595e32869f> ("<MAINTAINERS: Mark some staging directories>")
indicated the ipx network layer as obsolete in Jan 2018,
updated in the MAINTAINERS file.
now, after being exposed for 3 years to refactoring, so to
remove the ipx network layer header files
additionally, there is no module that depends on ipx.h
except a broken staging driver(r8188eu)
