It looks like we're close to convergence on this first patch set. I sifted thru review comments and compiled a list of items for follow-on work. I hope it's OK to use etherpad for this: https://etherpad.wikimedia.org/p/netdev-swdev-todo Feel free to edit as needed and claim an item if you intend to work on it. Don't turn the etherpad into a discussion board...try to keep it as list of work items. I don't think any of these items should hold up current patch set. -scott On Thu, Nov 27, 2014 at 2:40 AM, Jiri Pirko <jiri@...nulli.us> wrote: > Hi all. > > This patchset is just the first phase of switch and switch-ish device > support api in kernel.
