[dpdk-dev] [PATCH v7 3/9] app/testpmd: add GENEVE header option length support

[Shiri Kuzin]

From: Viacheslav Ovsiienko <viacheslavo at nvidia.com>

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.
