Wei Fang e31a11be41 net: phylink: add missing supported link modes for the fixed-link ... Pause, Asym_Pause and Autoneg bits are not set when pl->supported is initialized, so these link modes will not work for the fixed-link. This leads to a TCP performance degradation issue observed on the i.MX943 platform. The switch CPU port of i.MX943 is connected to an ENETC MAC, this link is a fixed link and the link speed is 2.5Gbps. And one of the switch user ports is the RGMII interface, and its link speed is 1Gbps. If the flow-control of the fixed link is not enabled, we can easily observe the iperf performance of TCP packets is very low. Because the inbound rate on the CPU port is greater than the outbound rate on the user port, the switch is prone to congestion, leading to the loss of some TCP packets and requiring multiple retransmissions. Solving this problem should be as simple as setting the Asym_Pause and Pause bits. The reason why the Autoneg bit needs to be set, Russell has gave a very good explanation in the thread [1], see below. "As the advertising and lp_advertising bitmasks have to be non-empty, and the swphy reports aneg capable, aneg complete, and AN enabled, then for consistency with that state, Autoneg should be set. This is how it was prior to the blamed commit."
