This is based on an earlier patch from Eric Biederman adding forwarding between macvlans. I extended his approach to allow the administrator to choose the mode for each macvlan, and to implement a functional VEPA between macvlan. Still missing from this is support for communication between the lower device that the macvlans are based on. This would be extremely useful but as others have found out

This is another update based on feedback from MST and Stephen on the last patchset. Hopefully this series can be integrated and any further enhancements can be made on top of this patchset. v8: - Made the failover managment routines more robust by updating the feature bits/other fields in the failover netdev when slave netdevs are registered/unregistered. (mst) - added support for handling

The main motivation for this patch is to enable cloud service providers to provide an accelerated datapath to virtio-net enabled VMs in a transparent manner with no/minimal guest userspace changes. This also enables hypervisor controlled live migration to be supported with VMs that have direct attached SR-IOV VF devices. Patch 1 introduces a new feature bit VIRTIO_NET_F_STANDBY that can be used
