You can disable checksum offload on veth pair in Linux.

In case of point-to-point, you can set the checksum offload flag
VNET_HW_INTERFACE_FLAG_SUPPORTS_TX_L4_CKSUM_OFFLOAD when you create demo
interface.
And need to calculate ip4_hdr_checksum in your tx node

VNET_BUFFER_F_OFFLOAD_IP_CKSUM set.

Can you please provide details about your setup, configuration, traffic flow
