Subject: [PATCH net] net: lan966x: Fix port configuration when using SGMII interface
Date: Tue, 23 Jan 2024 09:15:14 +0100 [thread overview]
Message-ID: <20240123081514.3625293-1-horatiu.vultur@microchip.com> (raw)
In case the interface between the MAC and the PHY is SGMII, then the bit
GIGA_MODE on the MAC side needs to be set regardless of the speed at
which it is running.
Fixes: d28d6d2e37d1 ("net: lan966x: add port module support")
