ISER_SendControl is used to send SCSI commands, SCSI TMF?s, unsolicited
SCSI Data-out, SCSI Responses and iSCSI Asyncronous Message.
ISER_RC_T ISER_SendControl(
ISER_CONNECTION_HANDLE_T connectionHandle,
pISCSI_HEADER pHeader,
pISER_PDU_QUALIFIERS pPDUQualifiers );
Returns: ISER_GOOD or ISER_FAILED
connectionHandle The connection handle returned by
ISER_Connect
pHeader
A pointer to an iSCSI header.
pPDUQualifiers A pointer to a set
of qualifiers. The only qualifiers that need to be actually set are the ones
relevant to the iSCSI header.

Subject: RE: iSER API's
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).
Dan
Eddy,
What APIs are you
asking about? 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.

iSER API's
Is there any work afoot to design some
standard iSER API's?
