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.

My guess is that something isn't setup correctly when the reconfigure request is issued.
Comment 7 Matteo Croce 2017-11-10 19:18:23 UTC 
The problem is because qede_set_mtu() assumes that qdev->fp_array[*]->rxq are already allocated, but buffers are allocated in qede_init_fp_queue().

This worked until backport of

    netdev-dpdk: use rte_eth_dev_set_mtu.

which added a call to rte_eth_dev_set_mtu() in dpdk_eth_dev_queue_setup() which result in a crash.

A possile fix could be moving the rte_eth_dev_set_mtu() just after the rte_eth_dev_start() call, which allocates the fastpath descriptors

Hi Christian,

Based on you comment to this other bz ( https://bugzilla.redhat.com/show_bug.cgi?id=1531145#c10 ) I assume that this one will also fixed by the new package?
Comment 14 Christian Trautman 2018-02-08 18:29:48 UTC 
Hi Matteo,

We should verify on the Q Logic 45000 series as that was what the bug was originally reported on.

Bug 1531145 was effecting both cards (41000 and 45000) but I'd just like to run it on a 45000x to confirm. We are having trouble with our systems right now with the 45000x so once we have fixed those systems we will double check with that RPM on that card.

Thanks.

Jean once those systems are functional again please verify this bug is no longer present with the rpm provided in bug 1531145.

Comment 20 Timothy Redaelli 2018-05-03 15:00:18 UTC 
*** Bug 1531145 has been marked as a duplicate of this bug. ***
Comment 23 Jean-Tsung Hsiao 2018-05-21 15:55:47 UTC 
The fix has been verified.

Was able to add qede to OVS. Below is part of "ovs-vsctl list interface dpdk-10" output showing mtu setting was correctly done:

mtu                 : 1500
mtu_request         : []
name                : "dpdk-10"

Also, tested the mtu_request:

root@netqe9 ~]# vctl set interface dpdk-10 mtu_request=9000
[root@netqe9 ~]# vctl list interface dpdk-10
