[openib-general] APM support in openib stack

[Tang, Changqing]

Sorry, I find the function  'ib_sa_path_rec_get()'  in kernel code. Then
here is my question:

Is there any way (instruction) to fill in struct 'ib_sa_path_rec' inside
struct 'ib_cm_req_param' without using librdmacm.so ?

Thank you very much.
