CSIT-235: Switched Port Analyzer mirroring (SPAN) - IPv4
- add library for SPAN setup - add telemetry traffic script and a keyword to run it - add "telemetry" folders for python and robot libraries - move IPFIX libraries to these new folders - add first SPAN test case, mirroring IPv4 ICMP packets Change-Id: Ibca35f724c13662bf80dce2d7e2649d1a0b8676a Signed-off-by: selias <samelias@cisco.com>
