[Qemu-devel] [PATCH v3 0/3] net: convert NetClientState to QOM

[Stefan Hajnoczi <stefanha@redhat.com>]

This series converts NetClientState from a plain C struct to QOM.  This means
emulated NICs and netdevs now derive from the NetClientState base class.  There
should be no user-visible change.

Converting the net subsystem to QOM opens the door to the following
improvements which can be built on top of this series:

1. Lifecycle cleanup to make hotplug saner and allow associating a NIC with a
   new netdev at runtime.  Really we should use the QOM lifecycle!

2. Exposing NICs and netdevs in the QOM tree so they can be configured and
   inspected at runtime.

I have tested virtio and e1000 with -netdev tap and user.  Build tested all
targets on Linux host.

v3:
 * Due to a horrible accident with git-rebase(1), the commit message for Patch
   3/3 was chopped off and mistakingly replaced with Patch 2/3's message.  I
   have picked the dropped commit message off the floor and glued it back on to
   Patch 3/3. [Markus]

v2:
 * Use object_dynamic_cast() instead of adding net_is_tap() function [Paolo]
 * Use "tap-net-client" type name for win32 and unix tap [Paolo]

Stefan Hajnoczi (3):
  net: add public qemu_net_poll() function
  net: extract notify_link_status_changed() function
  net: convert NetClientState to QOM
