+Subject: [PATCH] Align NetworkContext::SetNetworkConditions better with devtools emulateNetworkConditions
+
+The former used values of 0 to disable particular throttles, while the
+later documents -1, and looks to be pretty much a direct client, and the
+only one. So make NetworkService handle everything <= 0 as a disable,
+clamping at intake of config.
