From bebb2a473a43c8f84a8210687d1cbdde503046d7 Mon Sep 17 00:00:00 2001 From: Moni Shoua Date: Tue, 23 May 2017 10:48:44 +0300 Subject: [PATCH] IB/core: Namespace is mandatory input for address resolution In function addr_resolve() the namespace is a required input parameter and not an output. It is passed later for searching the routing table and device addresses. Also, it shouldn't be copied back to the caller.
