From 2e960c97c6b9311bea90b775e21a4b99ac1d50dc Mon Sep 17 00:00:00 2001 From: Anoob Joseph Date: Fri, 7 Sep 2018 11:25:26 +0530 Subject: [PATCH] examples/ipsec-secgw: fix wrong session size Crypto devices, which support lookaside protocol, exposes security session size in addition to the crypto private symmetric session data size. For applications using the security capabilities, both these sizes need to be considered.
