Author: rscheff Date: Fri Sep 25 10:49:26 2020 New Revision: 366151 URL: https://svnweb.freebsd.org/changeset/base/366151 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.
