From my understanding, srp_dev->max_pages_per_mr can be equal to 1, in
case device will advertise it.
Is this understanding correct?
Will the code work in such case?
Hello Leon,
I'm not sure a HCA driver exists for which max_pages_per_mr == 1.
Additionally, I'm not sure such a driver would be useful because such a
driver would limit the maximum data transfer size for the iSER protocol
to 4 KB. That is too low to reach good performance.
Bart.
