From 7825ef61b703c017c2b4ae56007046f0acd3fee6 Mon Sep 17 00:00:00 2001 From: Amos Kong Date: Tue, 5 Nov 2013 09:17:40 +0100 Subject: [PATCH 08/25] net/e1000: update network information when macaddr is changed in guest RH-Author: Amos Kong Message-id: <1383643062-1844-3-git-send-email-akong@redhat.com> Patchwork-id: 55369 O-Subject: [RHEL-7.0 qemu-kvm PATCH 2/4] net/e1000: update network information when macaddr is changed in guest Bugzilla: 922589 RH-Acked-by: Vlad Yasevich RH-Acked-by: Alex Williamson RH-Acked-by: Xiao Wang RH-Acked-by: Michael S. Tsirkin Bugzilla: 922589 If we change macaddr in guest by 'ifconfig eth0 hw ether 12:12:12:34:35:36', the mac register of e1000 is already updated, but we don't update network information in qemu. Therefor, the information in monitor is wrong. This patch updates nic info when the second part of macaddr is written.
