Given that this is an open list, I cannot go into the details of the
Fishworks clustering architecture.  However, broadly speaking, the
architecture requires that all clustered resources are identical across
the heads.  This is impossible in the current IB architecture because the
partition datalinks are created by the driver itself based on events that
are external to the box, and thus there is no way to guarantee that ibd0
on each head will refer to the same pkey.

However, while Fishworks is the catalyst, as covered in the case
materials, the work stands on its own and brings IB into line with the
established administrative model for VLANs/VNICs with Ethernet.  That is,
IB partitions are modeled identically to Ethernet VLANs.  This is the
right answer for a large number of reasons (observability, administrative
consistency, ability to create partitions when the IB subnet manager is
down ...) that have nothing to do with Fishworks.

When they create the partition, they choose the name.  This works
identically to VLANs, VNICs, aggregations, and so forth.  They can
then rename the link if they want.
