Subject: Query on interface state post compute reboot

Hi Qi Zhang,

  In our environment with E810 card, we observe sometimes dpdk0 is up and dpdk1 port is not coming up after the host reboot.

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.

We tried to narrow down to commits that went in dpdk21.02 and i see the below commits has resolved the issue for us.

I tried cherry-picking this on dpdk20.11.4 and i don’t see the issue after compute reboot.

b1d08cb258cd3e7757f2727381f59fa66d9d78b5 net/ice/base: read option ROM combo version from CIVD  ===>>> Commit in which issue is not seen.

This Commit is dependent on the below 3 commits.

eb1f31fad3150e06aab0f8db61117ac594b564f9 net/ice/base: refactor interface for flash read

f44382091895ae9a477247e995811bc940fdecdb net/ice/base: allow reading inactive flash security revision

c897f535e3a7899a4cbe0cdaaa8ba88761b95038 net/ice/base: allow flash read with arbitrary size

Can you please help us understand if these commits have any reference to the port states while host reboot.

I searched in internet for bug report on this fix but could not find any. Please let me know if any bug report is there for this commits

Thanks,

Pavan
