We are having the same problem for iscsi. For qla4xxx and cxgb3i and 
bnx2i, we would like to add driver specific attrs to the iscsi 
session/connection which are like FC's rport struct.

I was hoping if at least the classes provide an API to add driver 
specific attrs similar to how scsi-ml does, then it would be ok?
