ULP's can use this API to create/destroy SRQ's with the same
characteristics for implementing a logic that aimed to save resources
without significant performance penalty (e.g. create SRQ per completion

ULP).

Why did you call it "srq_set.c" and not "srq.c"?
because it's not a SRQ API but SRQ-set API.
I would say that it is SRQ-pool and not SRQ-set API.
If you have some other idea for an API, please share with us.
I've created this API in core layer to make the life of the ULPs easier
and we can see that it's very easy to add this feature to ULPs and get a
big benefit of it.
Thanks
