Followup on the work started by Thomas to free some space in the mbuf
structure.
This series applies on top of Thomas v3 series [1] and drops the seqn
field that had been deprecated.

The seqn mbuf field is deprecated.
It is currently hacked for debug purpose, it could be changed to a
dynamic field but I see little value in the debug info it offers.

The reorder library used sequence numbers stored in the deprecated field
seqn.
It is moved to a dynamic mbuf field in order to allow removal of seqn.

As announced in the deprecation note, the field seqn is removed to give
more space to the dynamic fields.
This is how the mbuf layout looks like (pahole-style):

Could you have a separate application-specific dynamic field here?

Could you change symbol name to rte_event_dev_selftest_seqn_dynfield_offset()
to limit the scope only to self test. also, it is not required to expose
rte_event_test_seqn_dynfield_register() in that case.

Ack for a test app dynamic field.
On the second comment, I'll wait for Thomas respin.

How about moving this to rte_eventdev_pmd.h and make it a pmd only API?
=> rte_event_pmd_ prefix
I would mark it rte_internal too.

Followup on the work started by Thomas to free some space in the mbuf
structure.
This series applies on top of Thomas v4 series [1] and drops the seqn
field that had been deprecated.

Changelog since v1:
- rebased on latest Thomas series,
- introduced a specific seqn for the eventdev test app,
- moved eventdev seqn as a pmd only thing,
David Marchand (9):
event/dpaa2: remove dead code
crypto/scheduler: remove unused internal seqn
net/ark: remove use of seqn for debug
reorder: switch sequence number to dynamic mbuf field
dpaa: switch sequence number to dynamic mbuf field
fslmc: switch sequence number to dynamic mbuf field
eventdev: switch sequence number to dynamic mbuf field

The seqn mbuf field is deprecated.
It is currently hacked for debug purpose, it could be changed to a
dynamic field but I see little value in the debug info it offers.

The reorder library used sequence numbers stored in the deprecated field
seqn.
It is moved to a dynamic mbuf field in order to allow removal of seqn.

The eventdev drivers have been hacking the deprecated field seqn for
internal test usage.
It is moved to a dynamic mbuf field in order to allow removal of seqn.
Signed-off-by: David Marchand <david.marchand@redhat.com>

Changelog since v1:
- split eventdev test app changes from this patch (moved to next patch),
- moved seqn as a pmd only API, fixed namespace and marked as internal,

The order test stored a sequence number in the deprecated mbuf field
seqn.
It is moved to a dynamic field in order to allow removal of seqn.

more space to the dynamic fields.
This is how the mbuf layout looks like (pahole-style):
