+pppd: Retain foreign default routes on Linux
+
+On Linux, when pppd attempts to delete its default route it does not fill
+the rt_dev field of the struct rtentry used to match the system default route.
+As a consequence, pppd happily deletes any default route even if it belongs
+to another interface.
+
+This patch makes pppd fill out the rt_dev field so that only own default
+routes are ever matched.
