> item
>
> 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 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.
