Do you have a working setup for MLX4 in DPDK 17.11? I can start from
scratch to build a new VM.
Giving all the information I gathered so far from DPDK, I can't seem
to make it work in my VM.
This is my VM info in case it is needed.
A Standard_DS3_v2 instance from Azure. (one of these models support AN)
Kernel 4.11.0-1016-azure, (I think from somewhere I saw that 4.14
kernel is required for the DPDK solution in
MS Azure to work. So I tried to update kernel to 4.14, but It didn't
seem to help solve the MLX4 driver problem)
Distributor ID: Ubuntu
Description: Ubuntu 16.04.3 LTS
