svn commit: r363380 - head/sys/netinet/cc

[Richard Scheffenegger]

Author: rscheff
Date: Mon Jul 20 23:47:27 2020
New Revision: 363380
URL: https://svnweb.freebsd.org/changeset/base/363380

Log:
  Add MODULE_VERSION to TCP loadable congestion control modules.
  
  Without versioning information, using preexisting loader /
  linker code is not easily possible when another module may
  have dependencies on pre-loaded modules, and also doesn't
  allow the automatic loading of dependent modules.
  
  No functional change of the actual modules.
