tests: tapv2, tunv2 and af_packet interface tests for vpp

Tests gso/gro-coalesce features on tapv2, tunv2 and af_packet
interfaces to ensure that packet transmission is enabled correctly
for various MTU sizes and interface combinations in bridged and
routed topologies for IPv4 and IPv6. Interface tests are
dynamically generated at run time from the config file
vm_test_config.py.

Type: test
