  IB/mthca: Remove "stop" flag for catastrophic error polling timer
  IPoIB: Double default RX/TX ring sizes
  IPoIB/cm: Reduce connected mode TX object size
  IB/ipath: Use IEEE OUI for vendor_id reported by ibv_query_device()
  IPoIB: Use dev_set_mtu() to change mtu
  IPoIB: Use rtnl lock/unlock when changing device flags
  IPoIB: Get rid of ipoib_mcast_detach() wrapper
  IPoIB: Only set Q_Key once: after joining broadcast group
  IPoIB: Remove priv->mcast_mutex
  IPoIB: Remove unused IPOIB_MCAST_STARTED code
