Good question.

I am guessing that they are exactly noop stubs, and the real 
point is to have a socket associated with an iSER RDMA connection.

My question is why? Unless the attempt is to allow upgrading
an iSCSI stream connection to an iSER connection I don't see
why an iSER RDMA connection is in any more of a need for having
a proxy socket than any other RDMA connection.

I really don't see the benefit of having a "socket" that is
not truly integrated with the host stack. What socket attributes
are being sought? And how is it unique to iSER as opposed to
RDMA in general?
