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 Mingyu Shi 2021-07-22 08:03:07 UTC 
Description of problem:
Changed ethtool settings, then modify the other settings of this interface(or even just touch it), the ethtool settings will get back to the default.

Version-Release number of selected component (if applicable):
nmstate-1.1.0-0.7.alpha7.el8.noarch
nispor-1.1.1-1.el8.x86_64
NetworkManager-1.32.2-1.el8.x86_64

How reproducible:
100%

Steps to Reproduce:
In here using veth to reproduce, but the issue also impacts physical NIC:

# set all ethtool.feature to false
nmstatectl apply << EOF -
interfaces:
- name: veth0
  type: veth
  state: up
  ethtool:
    feature:
      highdma: false
      rx-checksum: false
      rx-gro: false
      rx-gro-list: false
      rx-vlan-hw-parse: false
      rx-vlan-stag-hw-parse: false
      tx-checksum-ip-generic: false
      tx-checksum-sctp: false
      tx-generic-segmentation: false
      tx-gre-csum-segmentation: false
      tx-gre-segmentation: false
      tx-ipxip4-segmentation: false
      tx-ipxip6-segmentation: false
      tx-nocache-copy: false
      tx-scatter-gather-fraglist: false
      tx-sctp-segmentation: false
      tx-tcp-ecn-segmentation: false
      tx-tcp-mangleid-segmentation: false
      tx-tcp-segmentation: false
      tx-tcp6-segmentation: false
      tx-udp_tnl-csum-segmentation: false
      tx-udp_tnl-segmentation: false
      tx-vlan-hw-insert: false
      tx-vlan-stag-hw-insert: false
  veth:
    peer: veth0_p
EOF
nmstatectl show veth0 # all ethtool.feature are "false"
nmstatectl apply << EOF -
interfaces:
- name: veth0
  type: veth
  state: up
EOF
nmstatectl show veth0

Actual results:
some ethtool.feature change back to "true"

Expected results:
Preserved ethtool settings

Upstream patch: https://github.com/nmstate/nmstate/commit/13da783fe133755420874abde10f5a82105e42e5
Comment 5 Mingyu Shi 2021-08-11 12:11:05 UTC 
Verified with versions:
nmstate-1.1.0-3.el8.noarch
nispor-1.1.1-1.el8.x86_64
NetworkManager-1.32.4-1.el8.x86_64

Changed ethtool settings, then reapply, change mtu etc, ethtool settings preserve.
