From c823434174da3d6c632de2540ee70f105fe65fcc Mon Sep 17 00:00:00 2001 From: Tejasree Kondoj Date: Sat, 25 Sep 2021 21:05:32 +0530 Subject: [PATCH] test/crypto: add UDP-encapsulated IPsec cases Added tests to verify UDP encapsulation with IPsec. The tests have IPsec packets generated from plain packets and verifies that UDP header is added. Subsequently, the packets are decapsulated and then resultant packet is verified by comparing against original packet.
