From 153a58c6d8976f289b52e6652932c1cb28a2eacd Mon Sep 17 00:00:00 2001 From: Ronald Wahl <ronald.wahl@raritan.com> Date: Tue, 31 Oct 2023 13:20:05 +0100 Subject: [PATCH] net: ethernet: ti: am65-cpsw: rx_pause/tx_pause controls wrong direction The rx_pause flag says that whether we support receiving Pause frames. When a Pause frame is received TX is delayed for some time. This is TX flow control. In the same manner tx_pause is actually RX flow control.
