pkt_gen: STC - Imix Genome Support
This patch adds Imix-Genome support to STC. 1. Imix, of type genome, is included in traffic configuration. 2. The genome is converted to appropriated weights and pkt-sizes. 3. Throughput test is run with imix-configuration. 4. genome configuration is added to results. 5. Added Reporting of Average-Frame-Size - if IMIX is configured. 6. Updated genome comments 7. Clarified the reference to RFC 6985. JIRA: VSPERF-521 Change-Id: I813efb66338ee1d1320a01ce5e0834180461120c Signed-off-by: Sridhar K. N. Rao <sridhar.rao@spirent.com>
