3.16.7-ckt8 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Ilya Nelkenbaum <[email protected]> commit c2be9dc0e0fa59cc43c2c7084fc42b430809a0fe upstream. When marshaling a user path to the kernel struct ib_sa_path, we need to zero smac and dmac and set the vlan id to the "no vlan" value. This is to ensure that Ethernet attributes are not used with InfiniBand QPs.
