From ec1a695daa7390a6c24e3b28d3956f194cba2cb5 Mon Sep 17 00:00:00 2001 From: Jo-Philipp Wich Date: Fri, 13 Jan 2017 16:38:22 +0100 Subject: [PATCH] kernel: ar8327/ar8337: disable ARL access code to avoid lockups (FS#384) Running ar8327_get_arl_entry() early after boot leads to MDIO related system lockups on several devices using this driver. Since dumping the ARL table contens is an optional, uncritical feature, simply disable the code for now.
