With this change there won't be any e= xample of the legacy ipsec code path. Applications over DPDK take ipsec-sec= gw as an example and IPSec is a major use case for customers. There may als= o be performance differences in the two code paths. Atleast on NXP platform= s I saw 5-7% drop when the patches were originally submitted. Not sure what= is the current state. I feel it is worth notifying the users that the original codepath is gettin= g deprecated, so that they can plan to move to new IPSec APIs. -Akhil
