From de274be32cb288d96b91494aeaafccc34cf4e00f Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Tue, 8 Jun 2021 14:16:51 +0300 Subject: [PATCH] net: dsa: felix: set TX flow control according to the phylink_mac_link_up resolution Instead of relying on the static initialization done by ocelot_init_port() which enables flow control unconditionally, set SYS_PAUSE_CFG_PAUSE_ENA according to the parameters negotiated by the PHY.
