This is a known bug which is mentioned in the release notes:
http://wiki.centos.org/Manuals/ReleaseNotes/CentOS6.3#head-d261fbe9e9ee7564690adf254c8c794cc561666f
You could try the CentOS-Plus kernel - it contains a patch that should fix this problem (bugs.centos.org/view.php?id=4586)

Installed kernel-2.6.32-279.1.1.el6.centos.plus.x86_64 per recommendation this morning. 8021q/bonding VLAN tagging issues are resolved.

Q: Any idea when the patch will be applied to upstream ??

The kernel released today (http://rhn.redhat.com/errata/RHBA-2012-1104.html) reads like it solves this issue. The patches previously present in the CentOS-Plus kernel seem to be in this package (kudos to toracat). Once the release announcement is there please retest with the new upstream kernel.
