The Geneve tunneling protocol is designed to allow the user to specify some data context on the packet. The GENEVE TLV (Type-Length-Variable) Option is the mean intended to present the user data.
In order to support GENEVE TLV Option the new rte_flow item "rte_flow_item_geneve_opt" is introduced. The new item contains the values and masks for the following fields: -option class -option type -length -data The usage example: "flow create 0 ingress pattern eth / ipv4 / udp / geneve vni is 100 / geneve-opt class is 5 length is 1 type is 0 data is 0x66998800 / end actions count / drop / end" New item will be added to testpmd to support raw encap/decap action. v5: -added Devx function to def file. v4: - fixed setting option length. - fixed testpmd calculation of GENEVE option size. - updated documentation. v3: - updated documentation. v2: - removed pedantic.
