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. RELENG_5_3 candidate?
