The netstack GRO receive path validates L4 checksums before marking packets as RX checksum validated for gVisor. That validation is invalid for IPv4 fragments because TCP and UDP checksums cover the complete reassembled transport packet, not an individual fragment. Keep validating the IPv4 header checksum, but let IPv4 fragments through to gVisor for reassembly without pre-validating TCP or UDP.
