[Devel] [PATCH RH7 0/3] net: openvswitch: add capability to specify ifindex of new links

[Andrey Zhadchenko]

CRIU is preserving ifindexes of net devices after restoration, but current Open
vSwitch API are not capable to do that. So we need to modify it, because
- Restoring net devices with random ifindex will lead to some excessive
work to restore master relationship.
- OVS device taking another link ifindex will likely cause some problems and
may snowball previous point.
- Although OVS daemon is not supported yet, it is holding some tables which
have ifindex.

Also I found a bug within OVS module - if for some reason netdevice_register
fails, OVS gracefully kills kernel. Luckily there are some patches to
fix that.
