Subject: [PATCH v2 09/10] staging: fsl-dpaa2/ethsw: register_netdev only when ready
Date: Tue, 13 Aug 2019 11:54:38 +0300	[thread overview]
Message-ID: <1565686479-32577-10-git-send-email-ioana.ciornei@nxp.com> (raw)
In-Reply-To: <1565686479-32577-1-git-send-email-ioana.ciornei@nxp.com>

The register_netdev() call should be made only when ready to process any
user request on the interface. Move the call to be the last one issued
in the probe sequence.

Reported-by: Andrew Lunn <andrew@lunn.ch>
Signed-off-by: Ioana Ciornei <ioana.ciornei@nxp.com>
