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.
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
