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.
