From 219d04992b689e0498ece02d2a451f2b6e2563a9 Mon Sep 17 00:00:00 2001 From: Paolo Abeni Date: Wed, 16 Dec 2020 12:48:34 +0100 Subject: mptcp: push pending frames when subflow has free space When multiple subflows are active, we can receive a window update on subflow with no write space available. MPTCP will try to push frames on such subflow and will fail. Pending frames will be pushed only after receiving a window update on a subflow with some wspace available. Overall the above could lead to suboptimal aggregate bandwidth usage. Instead, we should try to push pending frames as soon as the subflow reaches both conditions mentioned above. We can finally enable self-tests with asymmetric links, as the above makes them finally pass.
