[dpdk-dev] [PATCH] test/crypto-perf: support lookaside IPsec

[Akhil Goyal <gakhil@marvell.com>]

Added support for lookaside IPsec protocol offload.
Supported cases:
-AEAD
-Cipher+auth

Command used for testing:
./dpdk-test-crypto-perf -c 0xf -- --devtype crypto_octeontx2 --ptest
throughput --optype ipsec --cipher-algo aes-cbc --pool-sz 16384
--cipher-op encrypt --cipher-key-sz 16 --cipher-iv-sz 16 --auth-algo
sha1-hmac --auth-op generate --digest-sz 16 --total-ops 10000000
--burst-sz 32 --buffer-sz 64,128,256,512,1024,1280,2048

./dpdk-test-crypto-perf -c 0xf -- --devtype crypto_octeontx2 --ptest
throughput --optype ipsec --aead-algo aes-gcm --pool-sz 16384
--aead-op encrypt --aead-key-sz 32 --aead-iv-sz 12 --aead-aad-sz 16
--digest-sz 16 --total-ops 10000000 --burst-sz 32
--buffer-sz 64,128,256,512,1024,1280,2048
