218e99
218e99
If we change macaddr in guest by 'ifconfig eth0 hw ether 12:12:12:34:35:36',
218e99
the mac register of e1000 is already updated, but we don't update
218e99
network information in qemu. Therefor, the information in monitor
218e99
is wrong.
218e99
218e99
This patch updates nic info when the second part of macaddr is written.
