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 Karthik Sundaravel 2021-09-07 10:50:58 UTC 
Description of problem:
Unable to set the MTU for the DPDK ports.


How reproducible:


Steps to Reproduce:
nmcli con add type ovs-bridge conn.interface ovsbridge0 con-name ovs-bridge0 ovs-bridge.datapath-type netdev
nmcli con add type ovs-port conn.interface dpdkbond0 conn.master ovsbridge0 con-name ovs-dpdkbond0 ovs-port.bond-mode balance-slb 
nmcli c add type ovs-port conn.interface ovsbridge-port0 master ovsbridge0 con-name ovs-port-br
nmcli c add type ovs-interface slave-type ovs-port conn.interface ovsbridge-port0 master ovs-port-br  con-name  ovs-if-br-house 802-3-ethernet.mtu 9000
nmcli con add type ovs-interface conn.interface iface0 conn.master dpdkbond0 con-name ovs-iface0 ovs-dpdk.devargs 000:18:00.2 ovs-interface.type dpdk 802-3-ethernet.mtu 9000
nmcli con add type ovs-interface conn.interface iface1 conn.master dpdkbond0 con-name ovs-iface1 ovs-dpdk.devargs 000:18:00.3 ovs-interface.type dpdk 802-3-ethernet.mtu 9000

Actual results:


[root@dell-r640-oss-03 ~]# ip a
10: ovsbridge-port0: <BROADCAST,MULTICAST,PROMISC> mtu 9000 qdisc noop state DOWN group default qlen 1000

[root@dell-r640-oss-03 ~]# sudo ovs-appctl dpctl/show

Expected results:
The MTU of the DPDK interfaces are not set to 9000
Comment 3 Gris Ge 2022-01-18 08:02:43 UTC 
Acceptance criteria: NetworkManager should support changing MTU of OVS-DPDK interface. Detail could be found in comment #0
