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 delete uapi/linux/ipx.h and net/ipx.h header files for good. additionally, there is no module that depends on ipx.h except a broken staging driver(r8188eu)
