From fdaff83d1ee1519662c74e9b4e2b51d55007a659 Mon Sep 17 00:00:00 2001 From: Bruce Richardson Date: Wed, 27 May 2015 14:47:49 +0100 Subject: [PATCH] kni: query the name of an instance When a KNI object is created, a name is assigned to it which is stored internally. There is also an API function to look up a KNI object by name, but there is no API to query the current name of an existing KNI object. This patch adds just such an API.
