Subject: [RFC PATCH v3 net-next 01/24] net: dpaa2-switch: use extack in dpaa2_switch_port_bridge_join
Date: Mon, 12 Jul 2021 18:21:19 +0300	[thread overview]
Message-ID: <20210712152142.800651-2-vladimir.oltean@nxp.com> (raw)
In-Reply-To: <20210712152142.800651-1-vladimir.oltean@nxp.com>

We need to propagate the extack argument for
dpaa2_switch_port_bridge_join to use it in a future patch, and it looks
like there is already an error message there which is currently printed
to the console. Move it over netlink so it is properly transmitted to
user space.
