-Subject: [PATCH] codel: refine one condition to avoid a nul rec_inv_sqrt
-
-commit 2359a47671fc4fb0fe5e9945f76c2cb10792c0f8 upstream.
-
-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.
-
-To keep codel_vars_init() as efficient as possible, refine
-the condition to make sure rec_inv_sqrt initial value is correct
-
-Many thanks to Anton Mich for discovering the issue and suggesting
-a fix.
