Back out ipx.h:1.18, which introduced a Linux API compatibility field in the ipx_net data structure.  Doing so introduced a stronger alignment requirement for the address structure, which in turn propagated into other dependent data structures, which turns out not to be suported by the available IPX source code.  As a result, a number of user space applications, such as IPX routing components, failed to operate correctly.
