There are some issues in the overall solution, since ARPs sent over the broadcast group reach also nodes with partial membership their HCA generated pkey violation errors which is a bit annoying, the IBTA has been dealing with this for a while, not sure where it stands. I'm not aware to other issues. All in all, the approach taken by IPoIB is to always use the full form of a pkey e.g 0x8001 and not 0x0001 when dealing with the core helper functions and within ipoib internally and externally -- e.g in the sysfs (and also in the rtnl link ops I'm adding now) interfaces - of add/delete child and show the pkey.
