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.

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

The driver is correctly displayed when no vlanid is given.
