[dpdk-dev] [RFC] mark asym session-buffer non-reuseable

[Ayuj Verma <ayverma@marvell.com>]

This RFC proposes changes in asymmetric session usability of
transform structure. In current implementation asym xform is
seen as temporary entity that can be re-used by application
once sessions are initialized with it.

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, 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 buffers in session configure. 

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