<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal">We are working on kernel upgrade task recently [0].<o:p></o:p></p>
<p class="MsoNormal">After upgrade the kernel, we find several modules cannot pass build, due to data structure/function api change in kernel.<o:p></o:p></p>
<p class="MsoNormal">Here is the module list cannot pass build with the new kernel:<o:p></o:p></p>
<p class="MsoNormal">Mlnx-ofa_kernel<o:p></o:p></p>
<p class="MsoNormal">Intel-i40e<o:p></o:p></p>
<p class="MsoNormal">Intel-i40evf<o:p></o:p></p>
<p class="MsoNormal">Tpmdd<o:p></o:p></p>
<p class="MsoNormal">Intel-ixgbe<o:p></o:p></p>
<p class="MsoNormal">drbd<o:p></o:p></p>
<p class="MsoNormal">openvswitch<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">To fix the build failure, I plan to upgrade these packages to newer version, which supports CentOS 7.6.<o:p></o:p></p>
<p class="MsoNormal">This upgrade may cause other packages depend on these packages be upgraded also.<o:p></o:p></p>
<p class="MsoNormal">Take Mlnx-ofa as example, it is bound with DPDK. <o:p></o:p></p>
<p class="MsoNormal">Per [1], MLNX_OFED 4.5-1.0.1.0 supports CentOS 7.6.<o:p></o:p></p>
<p class="MsoNormal">Per [2], DPDK should be upgraded to 18.11, while our current DPDK is 17.11, and is bound with OVS.<o:p></o:p></p>
<p class="MsoNormal">And OVS upgrade may affect Neutron.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I need network team to help decide the upgrade strategy of DPDK/OVS.<o:p></o:p></p>
<p class="MsoNormal">Thanks.<o:p></o:p></p>
