RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Íñigo Huguet 2022-01-20 07:17:11 UTC
Update sfc driver including latest upstream patches.

There are not many patches to be included, but some of them are fixes and improvements that allow to support XDP in more scenarios, fixing some related errors as well.

Comment 3 Íñigo Huguet 2022-02-09 07:41:07 UTC
Hi Tianhao, getting reviews for the sfc merge requests is delaying longer than expected. I would wait a few more days and if not I will have to shift the DTM.

Alternatively, since I honestly don't expect any push back from reviewers, you could begin testing, if you wish and have the time.

Thanks.

Comment 4 Íñigo Huguet 2022-02-16 11:21:17 UTC
Hi @tizhao, any chances on getting this verified soon? We'll have to start requesting exceptions if this gets delayed, so better to go forward with it (if you have the time, of course). Same for BZ 1995444 and BZ 2042801.

Comment 5 Tianhao 2022-02-20 15:27:30 UTC

Based on the tier1 functional test results, set TESTED.

Comment 6 Íñigo Huguet 2022-02-21 07:11:53 UTC
Are those the correct jobs? They seem to be related to r8169, not sfc.

sorry, the jobs are incorrect. Thanks for pointing it out.

I see that the problem is when modprobing with param efx_separate_tx_channels=y.

This is a known bug that won't be fixed, see BZ 1931024

Comment 12 Tianhao 2022-03-01 06:49:17 UTC
Done code check.

The tier2 nic functional tests pass on kernel-4.18.0-370.el8 on sfc driver.

Test includes:
scaling: pass
setup topo via NetworkManager and reboot: pass

related job:
https://beaker.engineering.redhat.com/jobs/6335852

There is no regressions found in testing, based on the tier1 test results on dt kernel and tier2 test results on candidate kernel, set VERFIED.
