[v6,0/9] ethdev: introduce GENEVE header TLV option 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 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.

v6:
- added testpmd support for GENEVE option length.
- updated setting GENEVE option length value.

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.

Hi Shiri,

Can you please rebase on top of latest next-net, this set conflicts with GTP 
patchset.

Thanks,
