From 12a36c502cd905db7ce9af2cae4e6f8b4989b65e Mon Sep 17 00:00:00 2001 From: stephen hemminger Date: Fri, 18 Aug 2017 13:46:23 -0700 Subject: [PATCH] net: make net sysfs attributes ro_after_init The attributes of net devices are immutable. Ideally, attribute groups would contain const attributes but there are too many places that do modifications of list during startup (in other code) to allow that.
