After VXLAN decapsulation, such packets do not pass sanity checks in br_netfilter and are dropped, which causes the test to fail. Fix this by calculating and setting a valid IPv4 header checksum for the encapsulated packet generated by mausezahn, so that the packet is accepted by br_netfilter. Fixed by using the payload_template_calc_checksum() / payload_template_expand_checksum() helpers that are only available in v6.3 and newer kernels.
