[dpdk-dev] [PATCH v6 00/15] remove mbuf userdata

[Thomas Monjalon]

The mbuf field userdata (aliased as udata64)
was announced to be removed for two reasons:
  - applications, libraries and drivers used the same field
    for different purposes, with a risk of usage conflict.
  - this field always used 8 bytes even if unneeded

Some dynamic fields are created when needed to replace
the big static userdata field.
As a consequence, 8 bytes can be re-allocated to dynamic fields.

This mbuf layout change is important to allow adding more features
(consuming more dynamic fields) during the next year.


v6:
- ARK field types different for Rx and Tx
- replace macros with inline functions

v5: sent "timestamp series" by mistake

v4 (thanks Jerin, Nithin and Ed):
- move rte_node dynfield offset to hotter context in cache
- move test-eventdev dynfield offset to hotter context in cache
- split ARK user data for Rx and Tx + more ARK fixes

v3 (thanks Olivier):
- use typedef for new field types
- fix node field type
- initialize offsets to -1
- add more inline functions
- inline rte_security_dynfield_is_registered
- add PMD-specific userdata field for ARK

v2 (thanks David & Andrew):
- fix some indentations
- return -rte_errno consistently
- make some type casts more precise
- define dynfield types in macros
- hide field description in rte_security
- do not lookup security dynfield in ipsec-secgw
- do not use the existing timestamp field for other purpose
