As far as I can tell, the patch for tg3 was not inside the release candidates for the current kernel. I’ve tested 4.15-RC8 and it was not working. Then RC9 was released (no idea about it). Two days ago a brand new stable version was released. Will try it and see what happens.

I just checked the changelog and it mentions nothing related to tg3, tigon, timeout or broadcom. I would bet this patch is not in here yet. Here it is.

I will try to run more tests today. One with a 4.13.3 without the patch, to see if it breaks (and hence, the patch is the real fix). And another with 4.15 (with and without patch), to see if it is fixed and, in case it’s not, if the patch applies cleandly and works. Meanwhile, yesterday I wrote in another thread (with the same bug), asking people from there to double check our findings. Maybe they can take a look too, and see what happens.
