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.
