Oops - I'll add them!

eric.dumazet@gmail.com acked the networking ones, and I have a
smattering of others for the other patches. Given the review and
feedback, I don't have a huge number of acked/reviewed-bys. I tried
not to lose any after the first couple of revs, but I know I did some
things wrong early on.

I can prod some others who've contributed to add their tags, unless
there is a good reason for them not too.  I suspect it was just
because of partial/drive-by reviewing, but I don't know.

thanks!
