[Qemu-devel] [PATCH 0/4] Add nic link up/down emulation to e1000

[Mark McLoughlin]

Hi,
        Here's a small patch set which adds link up/down
emulation to e1000 via a "set_link" monitor command. This is
useful for people who want to e.g. test how applications
and/or the guest OS handles this condition.

        The command itself takes a VLAN ID and device index
in order to identify which device to modify. That's a bit
lame and could clearly by improved if the overall idea was
thought to be sound.

Thanks,
Mark.
