Hi all,
We are working on kernel upgrade task recently [0].
After upgrade the kernel, we find several modules cannot pass build, due to data structure/function api change in kernel.
Here is the module list cannot pass build with the new kernel:
Mlnx-ofa_kernel
Intel-i40e
Intel-i40evf
Tpmdd
Intel-ixgbe
drbd
openvswitch

To fix the build failure, I plan to upgrade these packages to newer version, which supports CentOS 7.6.
This upgrade may cause other packages depend on these packages be upgraded also.
Take Mlnx-ofa as example, it is bound with DPDK.
Per [1], MLNX_OFED 4.5-1.0.1.0 supports CentOS 7.6.
Per [2], DPDK should be upgraded to 18.11, while our current DPDK is 17.11, and is bound with OVS.
And OVS upgrade may affect Neutron.

I need network team to help decide the upgrade strategy of DPDK/OVS.
Thanks.
