Not able to calculate right ipv6 checksum

[Parangesnehal]

hi sir/mam,

we are trying to make load balancer , we are changing the source and destination IP and MAC and doing XDP_TX. but at the server end the packet is drop by linux network stack because of wrong ipv6 checksum calculation (we are not able to see or get packet at application layer) actually we are not calculating right checksum. can you please help us in it to resolve this issue.

thank you.
