> This series combines the work previously posted by Roopa, Robert and > myself. It's according to what we discussed at NFWS. The motivation > of this series is to: > > * Consolidate code between OVS and the rest of the kernel and get > rid of OVS vports and instead represent them as pure net_devices. > * Introduce a lightweight tunneling mechanism which enables flow > based encapsulation to improve scalability on both RX and TX. > * Do the above in an encapsulation unspecific way so that the > encapsulation type is eventually abstracted away from the user. > * Use the same forwarding decision for both native forwarding and > encapsulation thus allowing to switch between native IPv6 and > UDP encapsulation based on endpoint without requiring additional > logic > > The fundamental changes introduces in this series are: > * A new RTA_ENCAP Netlink attribute for routes carrying encapsulation > instructions. Depending on the specified type, the instructions > apply to UDP encapsulations, MPLS and possible other in the future. > * Depending on the encapsulation type, the output function of the > dst is directly overwritten or the dst merely attaches metadata and > relies on a subsequent net_device to apply it to the packet. The > latter is typically used if an inner and outer IP header exist which > require two subsequent routing lookups to be performed. > * A new metadata_dst structure which can be attached to skbs to > carry metadata in between subsystems. This new metadata transport > is used to provide a single interface for VXLAN, routing and OVS > to communicate through metadata. Series applied, but please take Alexei's endianness feedback into consideration.
