net: Add Open vSwitch kernel components. Open vSwitch is a multilayer Ethernet switch targeted at virtualized environments. In addition to supporting a variety of features expected in a traditional hardware switch, it enables fine-grained programmatic extension and flow-based control of the network. This control is useful in a wide variety of applications but is particularly important in multi-server virtualization deployments, which are often characterized by highly dynamic endpoints and the need to maintain logical abstractions for multiple tenants. The Open vSwitch datapath provides an in-kernel fast path for packet forwarding. It is complemented by a userspace daemon, ovs-vswitchd, which is able to accept configuration from a variety of sources and translate it into packet processing rules. See http://openvswitch.org for more information and userspace utilities. Signed-off-by: Jesse Gross <jesse@nicira.com>

openvswitch: Add SCTP support This patch adds support for rewriting SCTP src,dst ports similar to the functionality already available for TCP/UDP. Rewriting SCTP ports is expensive due to double-recalculation of the SCTP checksums; this is performed to ensure that packets traversing OVS with invalid checksums will continue to the destination with any checksum corruption intact.

mpls: Fix the openvswitch select of NET_MPLS_GSO Fix the OPENVSWITCH Kconfig option and old Kconfigs by having OPENVSWITCH select both NET_MPLS_GSO and MPLSO. A Kbuild test robot reported that when NET_MPLS_GSO is selected by OPENVSWITCH the generated .config is broken because MPLS is not selected.

ovs: Turn vports with dependencies into separate modules The internal and netdev vport remain part of openvswitch.ko. Encap vports including vxlan, gre, and geneve can be built as separate modules and are loaded on demand. Modules can be unloaded after use. Datapath ports keep a reference to the vport module during their lifetime. Allows to remove the error prone maintenance of the global list vport_ops_list.

openvswitch: Use regular GRE net_device instead of vport Using GRE tunnel meta data collection feature, we can implement OVS GRE vport.
