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.

Fixed In Version: ovirt-node-2.5.0-8.el6
Doc Type: Bug Fix
Doc Text:
Previously, changing network interface drivers from bnx2 to e1000 on VLAN tagged network interfaces would fail. The driver would revert to bnx2, and vendor information would no longer be displayed. This was because the VLAN tag changed the name of the interface, and the properties of the parent interface weren't parsed correctly. Now, the udev properties of the parent interface are used with the tagged interface, and the interface is populated with the correct vendor information. The bnx2 driver remains the selected driver instead of reverting to e1000.

Description of problem:
In vlan ENV, choose the bnx2 nic and configure it with dhcp, the nic driver change from bnx2 to e1000, and the vendor info will disappear. 

Version-Release number of selected component (if applicable):
rhev-hypervisor6-6.3-20120913.0.el6_3

How reproducible:
100%

Steps to Reproduce:
1. TUI Install RHEV-H.
2. Enter Network detail page, focus on nic driver (The nic driver show as bnx2).
3. Configure the bnx2 nic with DHCP and vlan ID (e.g. 20)
4. Focus in nic driver and vendor info again.
5. Disable network and check the nic driver.
  
Actual results:
1. Nic driver change from bnx2 to e1000 after configured in vlan ENV.
2. Vendor info will disappear too.
3. The bnx2 driver will back after disable network.

Expected results:
Configured network in vlan should not affect nic driver.

Comment 4 cshao 2012-09-20 10:13:17 UTC 
No such issue in RHEV-H 6.2 GA version, so it is a regression bug.
Comment 8 Fabian Deutsch 2012-10-12 13:50:07 UTC 
This only happens if a vlanid is assigned to the nic.

The driver is correctly displayed when no vlanid is given.
