I see. The CMA code (cma_resolve_ib_route) just calls ib_get_path_rec 
and if the latter fails returns error to its consumer. Two questions 
come into my mind here: a) is it the final version or you plan to extend 
the CMA to directly query the SA in that case? b) the code of 
ib_get_path_rec seems to just search the path in the index and return 
-ENODATA if nothing is found, does it also trigger an SA lookup for this 
path?

Or.
