We're facing a similar problem as WANG Xiaoguang, refer to http://groups.google.com/group/android-porting/browse_thread/thread/5031fb191f2f1a14
Our ppp0 interface is up but connections to the outside network won't go through. What are the changes you did to the enum to make it work? Do you think the problems are caused by the enum in the npioctl struct or the fact that pppd was ported to android, and perhaps then modified to directly use the ioctl interface w/ enums?
