From a2935a1cd85fc76198a1980abfeb6dc9a776dcf3 Mon Sep 17 00:00:00 2001 From: Siddharth Vadapalli Date: Tue, 21 Mar 2023 16:49:55 +0530 Subject: [PATCH] net: ethernet: ti: am65-cpsw: Simplify setting supported interface Convert the existing IF/ELSE statement based approach of setting the supported_interfaces member of struct "phylink_config", to SWITCH statements. This will help scale to newer PHY-MODES as well as newer compatibles.
