Hello,
We are using Mellanox NIC and it was working fine with the DPDK 20.08 and kernel version 3.14.25.
Now, we have upgrade the our linux kernel version to 4.19.97 and but fail during probe of the PCI device from the DPDK. DPDK version is 20.08 only.
This is the error we are getting with kernel 4.19.97.
