From: Tejasree Kondoj Date: Fri, 16 Jul 2021 10:44:47 +0000 (+0530) Subject: crypto/octeontx2: fix lookaside IPsec IV pointer X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=48c56b329498589e5b57072616e16a776f2d6579;p=dpdk.git crypto/octeontx2: fix lookaside IPsec IV pointer In case of AES-GCM/CCM, nonce/salt comes along with IV, hence can be copied in a single memcpy. This patch fixes the IV copy in lookaside IPsec outbound instruction.
