Macvtap is essentially a combination of the Macvlan driver and a Tap device.
A Macvtap interface combines the properties of these two; it is an virtual interface with a tap-like software interface.
With these driver i'm able to share a NIC to a VM without any bridged setup. In Libvirt its called "direct" which is much faster and for hosted server solutions much more efficient sharing public ips to VMs.

MacVTap support three modes:

1. Virtual Ethernet Port Aggregator mode
2. Bridge mode
3. Private mode

Libvirt XML:

<interface type='direct'>
<mac address='d0:0f:d0:0f:00:01'/>
<source dev='eth0' mode='bridge'/>

This is a standard feature on SR-IOV enabled nics by now.
Would be wonderful if it got implemented after 4 years :(
