<p class="MsoNormal">Hi Qi Zhang,<o:p></o:p></p>
<p class="MsoNormal"> In our environment with E810 card, we observe sometimes dpdk0 is up and dpdk1 port is not coming up after the host reboot.<o:p></o:p></p>
<p class="MsoNormal">On our debugging, we see the issue is seen with dpdk20.11.4 and dpdk20.11.5(not tested on previous versions) but not seen in dpdk21.02.<o:p></o:p></p>
<p class="MsoNormal">We tried to narrow down to commits that went in dpdk21.02 and i see the below commits has resolved the issue for us.<o:p></o:p></p>
<p class="MsoNormal">I tried cherry-picking this on dpdk20.11.4 and i don’t see the issue after compute reboot.<o:p></o:p></p>
