pkt_gen: STC- Live Results Support
This patch adds live-results reporting from STC traffic generator. STC reports per-port stream results every second. The results are written to two different files in results folder. Added configuration filename for stc-liveresults JIRA: VSPERF-598 Change-Id: I37de6b5f544355e9e0dd42936328551b59afe065 Signed-off-by: Sridhar K. N. Rao <sridhar.rao@spirent.com>
