IB/ipath: Use IEEE OUI for vendor_id reported by ibv_query_device()
The IB spe. for SubnGet(NodeInfo) and query HCA says that the vendor ID field should be the IEEE OUI assigned to the vendor. The ipath driver was returning the PCI vendor ID instead. This will affect applications which call ibv_query_device(). The old value was 0x001fc1 or 0x001077, the new value is 0x001175. The vendor ID doesn't appear to be exported via /sys so that should reduce possible compatibility issues. I'm only aware of Open MPI as a major application which depends on this change, and they have made necessary adjustments.
