The patch adds the GENEVE rte flow option length support to
command line interpreter. The flow command with GENEVE
option items looks like:
flow create 0 ingress pattern eth / ipv4 / udp / geneve vni
is 100 optlen is 2 / end actions drop / end
The option length should be specified in 32-bit words, this
value specifies the all options length in the GENEVE header.
