+pppd: Fill in default gateway on Linux
+
+On Linux, when pppd creates the default route, it does not set the peer
+address as gateway, leading to a default route without gateway address.
+
+This behaviour breaks various downstream programs which attempt to infer
+the default gateway IP address from the system default route entry.
+
+This patch addresses the issue by filling in the peer address as gateway
+when generating the default route entry.
