Title:
[RFE] SR-IOV accelerated OVS integration
Status in neutron:
Fix Released
Bug description:
SR-IOV accelerated Open vSwitch significantly improves the performance of OVS
while maintaining its core functionality.
The idea is to leverage SR-IOV technology with OVS control plane management.
Change on the neutron side:
1. extend the OVS mechanism driver to bind direct port
The vif change are:
The mechanism driver will send new vif type to nova which will create hostdev
interface (SR-IOV VF passthrough) and will look up the SR-IOV VF representor
and plug it to the br-int
kernel changes for tc offloading support are merged in 4.8
ovs patches for using tc offloading can be found here
