Subject: IXGBE LSC IRQ issue
Hello,
We recently ran into an issue with DPDK 20.11 for the IXGBE driver operating in 10G \
BASE-T mode. We have been able to replicate this behavior using dpdk-testpmd and do \
not see any recent/pertinent updates, so we are hopeful someone may be able to advise \
based on the information provided below. On the surface, based on our investigation, \
it would appear the current link-down transition logic does not correctly preserve \
IRQ mask configurations, specifically LSC, when a link partner causes some sort of \
slow or bounced link down event. Background:
We recently started using a new 3rd party traffic generator card for testing our \
application. We found when using this card in 10G BASE-T mode and toggling link \
up/down, it would correctly cause our application to detect the port to be down in \
our DPDK design. However, the link down event handling by the DPDK IXGBE driver \
appears to permanently disable its LSC IRQ detection on the first port down event \
such that any subsequent link up or down events from the external test card on this \
port would no longer be detected. The only way to restore link up was to restart the \
DPDK port in our design (stop/start). Having looked at this a bit, we switched over \
to the classic testpmd application and observed the exact same behavior.
Here is the data we believe you would find interesting:

With the above "log-err" additions, we have provided the following results. The first \
set of data below was generated using an older 3rd party traffic generator card to \
provide "good" results that show the IXGBE driver working correctly. Following that \
are the non-working (bad) logging results for the new traffic generator card. Both \
3rd party cards correctly transition between down and up states.

<nothing happens as LSC IRQ is not enabled due to above link-down sequence>
Let me know what additional data can be provided to help root cause this.
