Merge branch 'bnx2x-next'
Yuval Mintz says: ==================== bnx2x: SR-IOV patch series (With the exception of the first patch) This series contains IOV-related patches, where the main changes are related to the driver's IOV-support backbone - it adds a new workqueue for IOV related tasks and removes the vfop mechanism from the driver. Please consider applying this series to `net-next'. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
