170kB patch - how to handle?

[Bartosz Fabianowski]

Good day

I would like to improve the audio/libvorbis port by optionally patching 
in the aoTuV psychoacoustics, which are considered to be superior to 
stock libvorbis. However, the patch file that does this is ~170kB in 
size. I am wondering whether it is OK to put such a large file directly 
into the ports tree or if it should be downloaded as a distfile by each 
user. Is there any guideline on which would be the correct method? I 
would hate for my suggestion to be rejected by the port's maintainer due 
to me getting a formality like this wrong.

Thanks,
- Bartosz
