CSIT-675: SRv6 performance tests
- update L1 KWs - update L2 KWs - tests with one SID (no SRH insertion) - tests with two SIDs (SRH inserted) and decapsulation - tests with two SIDs (SRH inserted) without decapsulation - enabled packet traces and logged packet traces in the test case tear down if test failed Change-Id: I3a0f4c350eed3f42509c6d49e832faa78fe64dbb Signed-off-by: Jan Gelety <jgelety@cisco.com>
