Yes, I was running some tests to make sure this didn't cause us
any grief.

In fact very aggressive "auto corking" would help my traffic flow.
I haven't yet tried locally reverting the patch that stopped
auto corking being quite as effective.
(I might even try setting the limit lower than 2*skb_true_size.)
