The kernelpatch kpatch1.3.72 you can use directly for kernels 1.3.72 .. ??? but it should be easy to apply this patch to all kernels. By older kernels 'sk->protinfo.af_ipx.' must become 'sk->' . After applying this patch please rebuild mars_nwe (make clean) for getting notice of new ioctl call 'SIOCIPXNCPCONN'. This patch is only necessary to speed up mars_nwe. (ca. 30 .. 50 % ) Perhaps this patch will get a place in the kerneldistribution one day. :) This kernelpatch was originally designed by Volker Lendecke. Martin
