This will create an issue in case of rte_security sessions.

Rte_security session create APIs were not updated when the provision for having Separate mempools for session and session private data was introduced.
As a result the number of entries in session_priv_pool should be double the number of Supported sessions - one for session and one for session priv data.

This should be fixed in rte_security API but this would mean an API breakage which cannot Be done before 20.11. So this patch need to be deferred till it is not fixed in rte_security.
Or we can have double the number of required entries in mempool.

I will double the number entries in mempool. Thanks!

Regards,
Akhil
