From 7c36507c2b8776266f50c5e2739bd18279953b93 Mon Sep 17 00:00:00 2001 From: Amos Kong Date: Thu, 17 Oct 2013 15:02:49 +0800 Subject: net/e1000: update network information when macaddr is changed in guest 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.
