Thinking seriously about it. I also implemented a nasty hack for including a ppp device in a bridge. Conceptually not much to it, but for detecting broadcast packets being sourced by the ppp device, i looked at the ip header. I'm sure this will cause some serious frowning from those who like to keep layer 3 out of layer 2 :). The rest of the implementation is fairly straightforward. I allow a mac address to be assigned to a ppp device and then do some skb cloning and header surgery (general muckery) to make sure the header looks right depending on what kind of device it came from and where it is going. I also have use the vtun tap device in the bridge and am pretty happy with it (but unfortunately it can't replace my ppp hack). I would like to move the data transport part to the kernel, but haven't had a chance to look at it yet. > > -- Nikolay Datchev > > On Sun, 5 May 2002, J.
