Just to clarify issues for discussion our work on the SQATGT driver
centered exclusively on the target component of the Qlogic driver.
Our work focused on providing an SCST equivalant to the tcm_qla2xxx.c
driver which the in-kernel implementation of the Qlogic target driver
uses to interface with the TCM target core. The {scst,tcm}_qla2xxx
drivers register a function dispatch structure with the Qlogic
hardware target driver, qla_target.c. These drivers take the actions
requested by the hardware driver and translate them into the necessary
target core processing functions.
As I have indicated the scst_qla2xxx driver could be distributed
separately from the kernel since it only relies on symbols which are
exported from the Qlogic driver. I'm not familiar with IB and such
but it seems to be a reasonable architecture for both camps of
interest to collaborate on.

Let us know when that becomes available since we would certainly like
to be assisting and supporting whatever the community agrees to as a
solution.

Have a good week.
