* Codel: avoid a nul rec_inv_sqrtJohn Crispin2012-08-021-0/+68
One condition before codel_Newton_step() was not good if we never left the dropping state for a flow. As a result rec_inv_sqrt was 0, instead of the ~0 initial value. codel control law was then set to a very aggressive mode, dropping many packets before reaching 'target' and recovering from this problem. Brought over from 3.5-stable Signed-off-by: Dave Taht <dave.taht@bufferbloat.net> SVN-Revision: 32950
