vRouter Hardware Offload Enablement

Registered by Jan Gutter on 2018-05-08

SmartNICs allow complex packet processing on the NIC. In order to support
hardware acceleration for them, Nova core needs modifications to support the
combination of VIF and vRouter plugging they support. This blueprint tracks a
hybrid SR-IOV and vRouter model to enable acceleration.

Note: In this blueprint, Contrail and Tungsten Fabric will be used interchangeably.
