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 of problem:
=======================
Improve error message for sap-hana-vmware profile when LRO is not supported. When I wanted to set LRO for eth0 and I didn't know that LRO is not supported, current error message didn't help me for understanding situation.
Version-Release number of selected component (if applicable):
=============================================================
tuned-2.9.0-1.el7.noarch
tuned-profiles-sap-hana-2.9.0-1.el7.noarch
How reproducible:
=================
Always when LRO (large-receive-offload) is not supported.
Steps to Reproduce:
===================
# cat /etc/tuned/sap-hana-vmware-variables.conf
sap_hana_vmware_nic=eno1
# tuned-adm profile sap-hana-vmware
# cat /var/log/tuned/tuned.log
...
2018-01-12 12:10:23,619 ERROR tuned.plugins.plugin_net: unable to save previous features, wanted to save: '['lro']', but read: '[('tx-vlan-offload', 'on'), ('tx-nocache-copy', 'off'), ('tcp-segmentation-offload', 'on'), ('\ttx-tcp-segmentation', 'on'), ('rx-vlan-offload', 'on'), ('tx-checksumming', 'on'), ('receive-hashing', 'on'), ('rx-all', 'off'), ('generic-receive-offload', 'on'), ('generic-segmentation-offload', 'on'), ('\ttx-tcp6-segmentation', 'on'), ('\ttx-checksum-ip-generic', 'on'), ('\ttx-scatter-gather', 'on'), ('rx-fcs', 'off'), ('scatter-gather', 'on'), ('\ttx-tcp-mangleid-segmentation', 'off'), ('rx-checksumming', 'on')]'
...
Following means that LRO is not supported:
# ethtool -K eno1 lro on
Cannot change large-receive-offload
Could not change any device features
# ethtool -k eno1 | grep large
large-receive-offload: off [fixed]
Actual results:
===============
Error which is not so much understandable for user.

Expected results:
=================
Something more readable:
ERROR: LRO is not supported

# ethtool -k eno1 | grep large
large-receive-offload: off [fixed]
IMHO the '[fixed]' is indicator that it's not supported. Tuned should check for it.
Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
