2021-10-08selftests: forwarding: Add IPv6 GRE flat testsAmit Cohen
Add tests that check IPv6-in-IPv6, IPv4-in-IPv6 and MTU change of GRE tunnel. The tests use flat model - overlay and underlay share the same VRF. These tests can be run with TC_FLAG=skip_sw, so then they will verify that packets go through hardware as part of enacp and decap phases.
