From 6a2968ee1ee2cc6fce30f6f5724442b34b1483b3 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Tue, 13 Feb 2024 06:32:42 +0000 Subject: net: add netdev_set_operstate() helper dev_base_lock is going away, add netdev_set_operstate() helper so that hsr does not have to know core internals. Remove dev_base_lock acquisition from rfc2863_policy() v3: use an "unsigned int" for dev->operstate, so that try_cmpxchg() can work on all arches.
