Bug ID: 1170
Summary: Link status is not correclty updated for E810 NIC (ice
driver) on Windows
Product: DPDK
Version: 22.11
Hardware: All
OS: Windows
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: ethdev
Assignee: dev@dpdk.org
Reporter: e.houet@deltacast.tv
Target Milestone: ---
Hello,
I have an issue regarding the link status when using a Intel E810 NIC with
DPDK.
I have a simple sample which simply loops, call `rte_eth_link_get` and prin=
ts
the result.
When using a E810 NIC, I have the following behaviour :=20
- At the start of the test, the cable is plugged in;
- I launch the sample, the link is reported as up (as expected)
- I unplug the cable
- The link is still reported as up in the sample (not expected).
- I stop the sample and relaunch it
- The link is reported as down by the sample (as expected)
- I replug the cable
- The link is still reported as down by the sample (not expected).
I looks like, once DPDK is started, the link status of the device is not
correctly updated.
When trying this with an XXV710 (i40e driver), i have no issue.
According to the Overview of Networking Drivers(
https://doc.dpdk.org/guides-21.02/nics/overview.html ), the ice driver is
compatible with "Link Status" and "Link Status Event" functionalities.
-------------------------------------------------------------
Setup:
- DPDK v22.11.1
- DDP : ice-1.3.30.0.pkg.
