From 9ea4742a55cadad1e0f52f2b4558f2b30512058e Mon Sep 17 00:00:00 2001 From: Sean Anderson Date: Thu, 18 Aug 2022 12:16:33 -0400 Subject: [PATCH] net: fman: Configure fixed link in memac_initialization memac is the only mac which parses fixed links. Move the parsing/configuring to its initialization function.
