As per the DPDK contribute guidelines, the subject line should use the imperative of the verb (like instructions to the code base).
http://doc.dpdk.org/guides/contributing/patches.html
Please change the subject lines for all patches in the patch set wherever it is required.

Also is it optimizing the stats update or fixing wrong stats update?

Adapter is agnostic to hardware, replace CPM with "crypto device"

Rephrase the commit message by adding:-
In case of crypto enqueue failures, even though backpressure flag is set to stop
further dequeue from eventdev the current logic does not stop dequeuing events
for max_nb events. This is fixed by checking backpressure just before dequeuing
events from event device.

Rephrase header with "Fix failed events" as the adding to circular buffer logic already exists
> 
> When many ops are failed to enqueue to eventdev, crypto adapter stores one
> event in buffer for later processing.
Rephase -> Circular buffer stores those events failed to enqueue to eventdev for
retrying later. Current implementation adds the same crypto op to circular buffer
instead of pointing all the ops in a batch. This fix updates the pointer to pointing to
correct ops in the batch.

[PATCH v3 1/5] eventdev/event_crypto: process event port's impl rel cap

[Ganapati Kundapura]

In the current implementation adapter queries event device's capability for
implicit release support.

This information is used to decide whether events are enqueued back as
NEW or FWD events.

This patch updates the adapter to query the port caps for implicit release
to decide on events enqueuing back as NEW/FWD events.

[Ganapati Kundapura]

Events enqueued to eventdev from the beginning of the circular buffer.
This leads to invalid or already freed events getting enqueued to eventdev

Fixed by enqueuing the events to eventdev from the head pointer of

[PATCH v3 4/5] eventdev/crypto: fix overflow in circular buffer

[Ganapati Kundapura]

In case of crypto enqueue failures, even though backpressure
flag is set to stop further dequeue from eventdev, the current
logic does not stop dequeueing events for max_nb events.

This is fixed by checking the backpressure just before
dequeuing events from event device.

Fixes: 7901eac3409a ("eventdev: add crypto adapter implementation")

[PATCH v3 5/5] eventdev/crypto: fix failed events

[Ganapati Kundapura]

Circular buffer stores events failed to enqueue to eventdev for
retrying later. Current implementation adds the same crypto op
to circular buffer instead of pointing all the ops in a batch.

This fix updates the pointer to pointing to correct ops in the batch.

    eventdev/crypto: fix failed events

    Circular buffer stores events failed to enqueue to eventdev for
    retrying later. Current implementation adds the same crypto op
    to circular buffer instead of pointing all the ops in a batch.

    This fix updates the pointer to pointing to correct ops in the batch.

    eventdev/crypto: fix overflow in circular buffer

    In case of crypto enqueue failures, even though back pressure
    flag is set to stop further dequeue from eventdev, the current
    logic does not stop dequeueing events for max_nb events.

    This is fixed by checking the back pressure just before
    dequeuing events from event device.

    eventdev/crypto: fix wrong offset used while flushing events

    Events enqueued to eventdev from the beginning of the circular buffer.
    This leads to invalid or already freed events getting enqueued to eventdev
    from the circular buffer.

    Fixed by enqueuing the events to eventdev from the head pointer of
    circular buffer.

    eventdev/crypto: select enqueue mode based on implicit release capability

    In the current implementation adapter queries event device's capability for
    implicit release support.

    This information is used to decide whether events are enqueued back as
    NEW or FWD events.

    This patch updates the adapter to query the port caps for implicit release
    to decide on events enqueuing back as NEW/FWD events.
