From 8a59359cb80f448923a7bc9f555d477e74547d7a Mon Sep 17 00:00:00 2001 From: Christoph Paasch Date: Wed, 8 Jan 2014 16:05:57 +0100 Subject: [PATCH] tcp: metrics: New netlink attribute for src IP and dumped in netlink reply This patch adds a new netlink attribute for the source-IP and appends it to the netlink reply. Now, iproute2 can have access to the source-IP. Signed-off-by: Christoph Paasch Signed-off-by: David S.
