This commit adds SR-IOV driver and new type of VIF to handle SR-IOV requests. This driver can work as a primary driver and only one driver, but only when kubernetes will fully support CNI specification. Now this driver can work in couple with multi vif driver, e.g. NPWGMultiVIFDriver. (see doc/source/installation/multi_vif_with_npwg_spec.rst) Also this driver relies on kubernetes SRIOV device plugin. This commit also adds 'default_physnet_subnets' setting, that should include a mapping of physnets to neutron subnet IDs, it's necessary to specify VIF's physnet (subnet id comes from annotation). To get details how to create pods with sriov interfaces see doc/source/installation/sriov.rst Target bp: kuryr-kubernetes-sriov-support Change-Id: I45c5f1a7fb423ee68731d0ae85f7171e33d0aeeb Signed-off-by: Danil Golov <d.golov@partner.samsung.com> Signed-off-by: Vladimir Kuramshin <v.kuramshin@samsung.com> Signed-off-by: Alexey Perevalov <a.perevalov@samsung.com>
