From 650adfeca2cdc49646d9536d965dd855de48c1ad Mon Sep 17 00:00:00 2001 From: "Sridhar K. N. Rao" Date: Mon, 12 Nov 2018 20:16:46 +0530 Subject: 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.
