See the recent dicussion about using pkey indexes at all. Each ipoib interface is assigned a pkey, by number, not index. If the SM has not supplied that pkey to the port then the ipoib should not come up. If the SM adds it later then it should come up, if it the SM removes it later then it should go down. The default ipoib interface uses the default pkey. If your network need ipoib to use a different pkey then you have to change the pkey number assignment when the ipoib interface is created, not magically attempt to autoconfigure. I believe you cannot safely change the broadcast GID once the ipoib interface has started.
