There was no explicit pointer field defined in the union - the byte ordering for 64-bit integer was not specified. Many fields have lesser lengths and byte ordering is crucial. - how the bit offset is applied to the immediate source field was not defined and documented - 64-bit integer size is not enough to provide MAC and IPv6 addresses In order to cover the issues and exclude any ambiguities the following is done: - introduce the explicit pointer field in rte_flow_action_modify_data structure - replace the 64-bit unsigned integer with 16-byte array - update the modify field flow action documentation [1] commit 73b68f4c54a0 ("ethdev: introduce generic modify flow action") Signed-off-by: Viacheslav Ovsiienko --- doc/guides/prog_guide/rte_flow.rst | 8 ++++++++ doc/guides/rel_notes/release_21_11.rst | 7 +++++++ lib/ethdev/rte_flow.h | 15 ++++++++++++--- 3 files changed, 27 insertions(+), 3 deletions(-) diff --git a/doc/guides/prog_guide/rte_flow.rst b/doc/guides/prog_guide/rte_flow.rst index 2b42d5ec8c..a54760a7b4 100644 --- a/doc/guides/prog_guide/rte_flow.rst +++ b/doc/guides/prog_guide/rte_flow.rst @@ -2835,6 +2835,14 @@ a packet to any other part of it. ``value`` sets an immediate value to be used as a source or points to a location of the value in memory.
