From ca46f9c834913fc5d5c196d70673375cdaba6b56 Mon Sep 17 00:00:00 2001 From: Mitsuru Chinen Date: Wed, 5 Dec 2007 22:31:47 -0800 Subject: [PATCH] [IPv6] SNMP: Increment OutNoRoutes when connecting to unreachable network IPv6 stack doesn't increment OutNoRoutes counter when IP datagrams is being discarded because no route could be found to transmit them to their destination. IPv6 stack should increment the counter. Incidentally, IPv4 stack increments that counter in such situation. Signed-off-by: Mitsuru Chinen Signed-off-by: David S.
