Hi, Ferruh
Yuying has already reviewed it days ago.
If you can, I hope you can change the status as soon as possible and try to
merge the code in RC4.
Thank you.

Subject: [PATCH v2 2/2] app/testpmd: fix SW L4 checksum in
multi-segments
Testpmd forwards packets in checksum mode that it needs to
calculate the checksum of each layer's protocol.
In process_inner_cksums, when parsing tunnel packets, inner L4
offset should be outer_l2_len + outer_l3_len + l2_len + l3_len.
In process_outer_cksums, when parsing tunnel packets, outer L4
offset should be outer_l2_len + outer_l3_len.

segments")

This seems OK. A similar miss is present for TCP case also.
Can you please do the same for that. Line 537

This change might not be required. As for normal packet (non-tunnel case)
l4_off = info->l2_len + info->l3_len; should be valid.
Please re-check.
I don't understand what you mean. I fix the code under the tunnel case, and I
didn't modify the code for the non-tunnel case.
Sorry, my bad.
