Change the protocol extraction dynamic mbuf usage from regiser API to
lookup API, so the application can decide to read the metadata or not
at the run time, in other words, PMD will check this at Rx queue start
time.
This design makes the API simple now: it just needs to export the name
string, not the whole dynamic mbuf data objects.
Signed-off-by: Haiyue Wang <haiyue.wang@intel.com>

v2: update the commit message, doc; and add the error handling for
dynamic mbuf lookup. Also keep the metadata format defination.

- Use ``rte_net_ice_dynf_proto_xtr_metadata_get`` to access the protocol
- extraction metadata, and use ``RTE_PKT_RX_DYNF_PROTO_XTR_*`` to get the
- metadata type of ``struct rte_mbuf::ol_flags``.
-
- The ``rte_net_ice_dump_proto_xtr_metadata`` routine shows how to
- access the protocol extraction result in ``struct rte_mbuf``.
+ The dynamic mbuf field for metadata uses "rte_pmd_dynfield_proto_xtr_metadata"
+ name with 4 byte size. And the related dynamic mbuf flag uses the name format
+ "rte_pmd_dynflag_proto_xtr_*" which ends with the protocol extraction devargs
+ name such as "ip_offset".

Change the protocol extraction dynamic mbuf usage from register API to
lookup API, so the application can decide to read the metadata or not
at the run time, in other words, PMD will check this at Rx queue start
time.
This design makes the API simple now: it just needs to export the name
string, not the whole dynamic mbuf data objects.
Signed-off-by: Haiyue Wang <haiyue.wang@intel.com>

v3: Fix 'regiser' typo in commit message.
v2: update the commit message, doc; and add the error handling for
dynamic mbuf lookup. Also keep the metadata format defination.

- metadata type of ``struct rte_mbuf::ol_flags``.
-
- The ``rte_net_ice_dump_proto_xtr_metadata`` routine shows how to
- access the protocol extraction result in ``struct rte_mbuf``.
+ The dynamic mbuf field for metadata uses "rte_pmd_dynfield_proto_xtr_metadata"
+ name with 4 byte size. And the related dynamic mbuf flag uses the name format
+ "rte_pmd_dynflag_proto_xtr_*" which ends with the protocol extraction devargs
+ name such as "ip_offset".

In case the dynamic mbuf field is shared by several PMDs, it seems to
be indeed a better solution.
Currently, the "union rte_pmd_proto_xtr_metadata" is still defined in
rte_pmd_ice.h. Will it be the same for iavf, and will it be factorized
somewhere? However I don't know where could be a good place.
There is already lib/librte_mbuf/rte_mbuf_dyn.h which is the place to
centralize the name and description of dynamic fields/flags used in
libraries. But I think neither structure definitions nor PMD-specific
flags should go there too. I'd prefer to have them in
drivers/net/<common-something>, but I'm not sure it is possible.
Also, it is difficult from the patch to see the impact it has on an
application that was using these metadata. Should we have an example
of use?
Thanks,
Olivier

May be new 'lib/librte_mbuf/rte_mbuf_dyn_pmd.h' for all PMDs specific ?
So that the application knows exactly how many *dynamic* things. Also,
a new API to query the dynamic information + dev_ops may be introduced
in next release cycle, then 'rte_pmd_mlx5_get_dyn_flag_names' can be
removed. And the application will be clean.
Currently, we use " #define __INTEL_RX_FLEX_DESC_METADATA__ " to fix the
duplicated definition, but the application have to include the two header
files like "rte_pmd_ice.h" / "rte_pmd_iavf.h"

Thanks your link in previous mail:
http://inbox.dpdk.org/dev/20191030165626.w3flq5wdpitpsv2v@platinum/
Original patch uses: Solution 1, provide static inline helpers to access to the
dyn fields/flags
Now now: Solution 2, without global variable export and helpers: the application
calls rte_mbuf_dynfield_register(&rte_pmd_ice_proto_xtr_metadata_param) to get
the offset, and store it privately.
https://patchwork.dpdk.org/patch/82165/
In v3 patch, I kept the metadata format, and rename it to be more generic:
'union rte_pmd_proto_xtr_metadata', but no dump function as the original design.

Rename the dynamic mbuf name to 'intel_pmd_xxx' format, so that the
Intel PMD which has the protocol extraction feature will share the
same dynamic field/flags space in mbuf.
Signed-off-by: Haiyue Wang <haiyue.wang@intel.com>
---
v4: "who register, who use", even the PMD has the duplicated code with
different name space, the defined API will help the application to
focus on the function itself that the PMD provides.
v3: Fix 'regiser' typo in commit message.
v2: update the commit message, doc; and add the error handling for
dynamic mbuf lookup. Also keep the metadata format defination.
