[ewg] Questions about CC in OFED

[Michael Zhang]

Hi everybody,

  I focus on the source code of  IB congestion control in OFED, such as CCT
related data structure and FECN/BECN process. But the only code related to
the congestion control mechanism is found in the module of
"infinipath-psm". As I know, psm works for MPI applications and actually I
haven't installed psm in our system. I have done experiment through IPoIB
and the congestion control still works that makes me confused.
  Could someone tell me where is the CC-related source code located besides
"infinipath-psm"? Or some functions are realized in hardware such as the
movement of CCT Index when receives BECN message?
  Thank you for your help!

Best,
Ziwen
