Hi all.

PMD for Google Virtual NIC says it is capab= le of IPV4 TX checksum offloading.

https://github.com/DPDK= /dpdk/blob/main/drivers/net/gve/gve_ethdev.c#L285

But according to my tests on Google Cloud, it is not doing that ipv4 chec= ksum tx offload.
I only managed to send a packet via DPDK if I calculate= the checksum myself.

Do you have any idea about t= hat?=C2=A0

Best,
