As of 2.6.34 the ixgbe driver does not support multiple queues for macvlan. Support for multiple queues for macvlan will come in a subsequent release. > > >Before I submit the patch, I want to understand the right index >assignment for both rar index and VMDQ index, when SRIOV enabled: >1.

Looks like ixgbevf secondary addresses are not >in receiver address filter, so macvlan on VF doesn't work. The VF driver does not support macvlan. Future releases may but there are no immediate plans to support it. - Greg Rose Intel Corp. Lan Access Division
