Modify sweep ping test cases
- Write separate sweep ping test cases for jumbo frames - Compute sweep ping end size from reported MTU on DUT interface - Set MTU on TG according to MTU on DUT interface - Log VPP packet traces on IPv4 and IPv6 tests failure - Remove VM_ENV tag from sweep ping test cases for jumbo frames Change-Id: I47aa7977bcff9c4366c67578aef542924a1d055b Signed-off-by: Juraj Sloboda <jsloboda@cisco.com>
