[dpdk-dev] [PATCH v3 7/8] app/crypto-perf: add support for DOCSIS protocol

[David Coyle <david.coyle@intel.com>]

Update test-crypto-perf app to calculate DOCSIS throughput numbers.

1 new parameter is added for DOCSIS:
--docsis-hdr-sz <n>

./dpdk-test-crypto-perf -l 3,4 --socket-mem 2048,0
--vdev crypto_aesni_mb_pmd_1 -n 1 -- --devtype crypto_aesni_mb
--optype docsis --cipher-algo aes-docsisbpi --cipher-op encrypt
--cipher-key-sz 16 --cipher-iv-sz 16 --burst-sz 32 --total-ops 20000000
--buffer-sz 1024 --silent --docsis-hdr-sz 17
