!! Well, gee, I wish this plan had been made public. I'd spent something between 3-6 months working full-time on spidernet issues. This was a lot of work and effort. Worse, this was *not* my main job; it was rather to help the neighbors prevent a disaster in the making. Certainly, I would not have spent any time on this, if I'd known someone else was also working to fix the same bugs. :-( > I totally understand difficultness of your effort that fixing spidernet > without decent documentation which we have, but the changes we made was > significantly large as you see if you diff gelic driver with current > spidernet driver (totally different), The differences are very large, because very large changes have been made to the spidernet. However, a diff between gelic and the old spidernet is much smaller. So I'm somewhat confused by this. Perhaps I am mistaken, and should read the code more carefully. > so the conclusion of discussion at > 3C common-linux wg (Sony, IBM and Toshiba) ?? What working group is this? This is the first time that I am hearing of it, and, as the only active spidernet maintainer, I'd hope to have been a part of suc discussion.
