Hi Haiyue,

Before the patch, the result of a specific hw parsing was stored in
m->udata on Rx and this information is supposed to used by an
application or a library, is that correct?

If this fields are going to be used by an application, I think you need
to provide an api to access to the fields.

Solution 1, do the same than in Slava's patch (flow metadata):

- provide a function to do the registration (something like
  rte_pmd_ice_proto_xtr_register()), that sets global offset and masks.
- export these global offset and masks
- provide static inline helpers to access to the dyn fields/flags

Solution 2, without global variable export and helpers:

- define the rte_mbuf_dynfield and rte_mbuf_dynflag structures in
  the .h as static const, so they can be used by the application
- to access to the dynamic fields/flags, the application calls
  rte_mbuf_dynfield_register(&rte_pmd_ice_proto_xtr_metadata_param) to get
  the offset, and store it privately. Then it uses the generic macros
  to access to the field.

I think it is quite dangerous not to return an error in case the
registration fails. If the application makes use of a helper (in case of
solution 1), it may crash if there is no verification in the helper.

Another thing that can be a problem: from what I see, the registration
of the dynamic field will always be done as soon as the ice port is
configured. But maybe the user does not want to use this feature, and
prefers instead to keep space in mbuf for another purpose. I think this
should be an option.

A possibility is to let the application do the registration through the
registration helper (still solution 1). If the application wants to use
this feature, it will first register the fields/flags, and they will be
filled by the PMD on rx if they are registered.

Just an observation: I wonder if it wouldn't be more efficient to
register a 3 consecutive flags, and use it as a value: 0=none, 1=vlan,
2=ipv4, 3=ipv6, ...
Unfortunately, there is no 'count' parameter to the
rte_mbuf_dynflag_register() function, but I think is doable easily.
