nx_packet_data_append overflows for a payload size set to max to achieve MTU ?

[Alexbruliau]

Hello,
I was wondering what will happens if nx_packet_data_append applied on a previously TCP packet with a payload set to (1500 - 20(ip_header) - 20(tcp_header).
I have the feeling that nx_packet_append will exceed nx_packet_data_end since you applied a header of 16 for the eth header to be aligned.
What am I missing ?

Best regards

Hi @Alexbruliau.

Thank you for reaching out.

I am unsure of the answer myself. I will ask a team member with more NetX Duo experience to look into this and provide feedback.

you can close it ! Its because I thought the payload size when creating the packet pool was to be set to 1514.
