    "content": "Due to the complex NVGRE_ENCAP flow action and based on the fact testpmd\ndoes not allocate memory, this patch adds a new command in testpmd to\ninitialise a global structure containing the necessary information to\nmake the outer layer of the packet.  This same global structure will\nthen be used by the flow command line in testpmd when the action\nnvgre_encap will be parsed, at this point, the conversion into such\naction becomes trivial.\n\nThis global structure is only used for the encap action.\n\nSigned-off-by: Nelio Laranjeiro <nelio.laranjeiro@6wind.com>\nAcked-by: Ori Kam <orika@mellanox.com>\n---\n app/test-pmd/cmdline.c                      | 118 ++++++++++++++++++\n app/test-pmd/cmdline_flow.c                 | 129 ++++++++++++++++++++\n app/test-pmd/testpmd.c                      |  15 +++\n app/test-pmd/testpmd.h                      |  15 +++\n doc/guides/testpmd_app_ug/testpmd_funcs.rst |  42 +++++++\n 5 files changed, 319 insertions(+)",
