using raw IPX sockets. While functional, this support is disabled using a flag that can't be changed from userspace, and google reveals no documentation or use of that flag anywhere. This eliminates a potential lock order reversal and code reentrance issue in which the output path reentered the input path in IPX. An alternative to removal would be to use the netisr, as a comment I added in 2005 suggests. While this change is fairly straight-forward, the lack of any consumers or the easy possibility of consumers (kernel modification and recompile required) suggests that this is simply an unused feature. Update README to remove this TODO, and a TODO regarding IPX/IP encapsulation which was also removed a few years ago. MFC after: 1 week
