When running the test on the Spectrum ASIC the generated packets are counted on the ingress filter and injected back to the pipeline because of the 'pass' action. The router block then drops the packets due to checksum error, as the test generates packets with zero checksum. When running the test on an emulator that is not as strict about checksum errors the test fails since packets are counted twice. Once by the emulated ASIC on its ingress filter and again by the kernel as the emulator does not perform checksum validation and allows the packets to be trapped by a matching host route. Fix this by changing the action to 'drop', which will prevent the packet from continuing further in the pipeline to the router block. For veth pairs this change is essentially a NOP given packets are only processed once (by the kernel).
