[dpdk-dev] [PATCH] doc: announce IPsec xform struct changes

[Anoob Joseph <anoobj@marvell.com>]

IPsec xform struct would be updated to include IPsec SA lifetime
configuration. The existing member 'esn_soft_limit' would only track
ESN. And as sequence number control is getting introduced,
'esn_soft_limit' may not indicate the number of packets processed.
Replace that with a new structure to cover all lifetime cases with
support for specifying both soft and hard lifetimes.

ESN control introduced by: http://patches.dpdk.org/project/dpdk/patch/20210713133542.3550525-4-radu.nicolau@intel.com/
