This set of changes introduces the ML2 mechanism driver for SR-IOV capable NIC based switching.
Please see the blueprint for more information.
The review is submitted in two parts:
- Part 1 (this part)
The Mechanism Driver to support port binding for SR-IOV virtual functions of
SRIOV capable switching NICs, such as Mellanox ConnectX Family.
Use configurable list of supported NIC vendor and product PCI ids to filter
devices to bind the SR-IOV port.
Use configurable agent_required option to require SRIOV L2 Agent
for bort binding.
- Part2
The SRIOV NIC Based L2 Agent.
Partially implements: blueprint ml2-sriov-nic-switch
