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:
"/ixgbe-3.6.7/src/ixgbe_main.c:5103:error:'struct net_device' has no member named 'tc_to_txq'"
"/ixgbe-3.6.7/src/ixgbe_main.c:5104:error:'struct net_device' has no member named 'tc_to_txq'"
Version-Release number of selected component (if applicable):
4. The driver can not be added into RHEL6.2 Beta (x86_64bit)
How reproducible:
Steps to Reproduce:
1. Download the latest driver from intel, ixgbe3.6.7
2. Extracting the tar package, and run "make"
3. "/ixgbe-3.6.7/src/ixgbe_main.c:5103:error:'struct net_device' has no member named 'tc_to_txq'"
"/ixgbe-3.6.7/src/ixgbe_main.c:5104:error:'struct net_device' has no member named 'tc_to_txq'"
Version-Release number of selected component (if applicable):
4. The driver can not be added into RHEL6.2 Beta (x86_64bit)
Actual results:
Expected results:
The driver should be OK.
Additional info: The driver 3.5.14 also fail
RHEL6.2 Beta kernel (2.6.32-202.el6.x86_64)
-->The driver ixgbe-3.6.7 can not be installed-->FAIL
RHEL6.1 RC3
-->The driver ixgbe-3.6.7 can be installed -->PASS
It is OS issue, since RHEL6.1 x86_64 is OK.
This isn't an OS bug, its the result of our ABI promise and a break that was fixed between 6.1 and 6.2. the tc_to_txq array was added to the net_device struct in 6.1, which allowed the ixgbe out of tree driver to build properly but breaks the RHEL ABI stability guarantee. 6.2 fixed the ABI breakage by moving that array to an ABI safe location, but requires a macro access for drivers to get to. Since we guarantee ABI, but not out of tree driver building, this is the correct solution. You can fix up the ixgbe sourceforge driver by replacing all instances of dev->tc_to_txq in the driver with this:
netdev_extended(dev)->qos_data.tc_to_txq
I'll attach a patch to make the modification for you.
