Subject: [PATCH v3 net-next 02/12] net: dsa: pass extack to dsa_port_{bridge,lag}_join
Date: Sun, 21 Mar 2021 00:34:38 +0200
Message-ID: <20210320223448.2452869-3-olteanv@gmail.com> (raw)
In-Reply-To: <20210320223448.2452869-1-olteanv@gmail.com>

From: Vladimir Oltean <vladimir.oltean@nxp.com>

This is a pretty noisy change that was broken out of the larger change
for replaying switchdev attributes and objects at bridge join time,
which is when these extack objects are actually used.
