Subject: test/crypto: add fragmented packet case
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=825ab5c31a74ce88514a9d57258f44ea81b3498d;p=dpdk.git

test/crypto: add fragmented packet case

Add fragmented plain packet test case in combined mode.
The test case leverages combined mode framework to generate
IPsec packet from a fragment and verify that headers are formed
correctly. The IPsec packet would be decapsulated and the plain
packet is compared against the original packet.
