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 added. The new item contains the values and masks for the following fields: -option class -option type -length -data New item will be added to testpmd to support match and raw encap/decap actions.

The GENEVE TLV option match must include all fields with full masks due to NIC does not support masking on option class, type and length. The option data length must be non zero and provided data pattern should be zero neither due to hardware limitations.
