Log:
  MFC r365546: cc_mod: remove unused CCF_DELACK definition
  
  During the DCTCP improvements, use of CCF_DELACK was
  removed. This change is just to rename the unused flag
  bit to prevent use of it, without also re-implementing
  the tcp_input and tcp_output interfaces.
  
  No functional change.
