BGL-free net stack
Hello all, for my diploma thesis, I've arranged to work on getting the DragonFlyBSD network stack[*] to run without the BGL. Now, it would be great if the code changes would become part of the project. So, my plan is to study the net code over easter vacation (it's been a long while since I last looked at it and I've never been a network guy in any case) and then post a preliminary roadmap on kernel@. At that point, everyone can give an opinion before any code gets written. Needless to say, I...
