This comes from pr 234878  on bugzilla, many people contributed patches there to create this update, my work has mainly been with cleaning up the patches and integrating in present ports tree, so credit is due to the various contributors there (jkim, Mario Lobo, lwhsu contributed patches, many other testing and suggestions)
I added patches to make additions 6.1.18 work. The module gave me a bcmp undefined symbol error, the fix I used comes from a post on the mailin lists 
Patch also includes a tentative entry for UPDATING.
- At present this compiles only on amd64, and while it produces a package on 11 and 12 it fails to work there.
- The patch includes repocopies of the version 5 ports as legacy versions. This will ensure some path for users who can't run the latest hardware/software. BTW these legacy ports could be updated to 6.0 later, AFAIK 6.0 has the same requirements as 5.x.
- I regenerated most of the patches to have them fresh
