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.

width and speed changes take effect. Without this patch, a link DOWN
physical state NOP command was causing the link width and speed settings

goes down (either by a SMP or some link physical error like link errors
exceeding the threshold).
