IIRC the immediate data (32 bits) is delivered in a
field in the structure returned by the cq poll function (which means that
the
SEND RDMA w/immediate does consume an rq work
request). The s/g info has no bearing on the immediate data.

Subject: [openib-general] Quick RDMA
Write with Immediate Data Item question
Hi,
Just a quick question I can't seem to find the answer to.
With an "RDMA Write with Immediate Data Item" transfer, in the CQE at the
destination (the thing that has the Immediate Data it), does the CQE also
contain the memory location where the message just got written too?
i.e. does the scatter/gather buffer member of the work completion
structure get filled in at all? Or do you just get the ImmdDataItem?
Thanks for your help.
Steve Wooding.
