Indeed on Linux the direction is towards a generic RDMA interface. CMA provides a generic CM abstraction, and the ib_verbs API is planned to extend over iWARP one way or another. The DM was deemed unnecessary, the API between iSCSI & SCSI and the underlying iSER enforced redesign of the iSER API to conform with iSCSI and SCSI rather then implement yet another layer between iSER and iSCSI/SCSI (namely DM).

The SCSI CLASS Driver to the Device Driver (Mini Port Driver) should have the same interfaces for iSER as it is available for iSCSI. If you mean between the Device Driver (Mini Port Driver) and the RNIC, that will probably be the RNIC vendors interface if they have implemented all or part of the iSER or Data Mover in the RNIC itself, or the RNIC vendor's interfaces to their version of the verbs (at least until the OS implements its own RDMA interfaces that implement the RDMA verbs). I believe that, over time, most OSs will have generic RDMA interfaces, which can be use by all certified RNIC hardware, and any application (user space or kernel space); in that case the iSER module will probably interface to that OS's RDMA interfaces. . . .
