> This enforces PMD to copy all key buffers during session setup time. Since
> life-time of sessions are small, so we can hold these buffers with session,
[AK] - what is you expected session lifetime? (2,3,50 packets?)
> reducing memcpy time by marking these as read-only so that PMDs which
> doesn’t require any manipulation of xform data can directly use these

> So, sending a proposal to mark xform as non-reusable till lifetime of session.
> This will help PMDs to reduce session setup time.
