From 03117a1e7db4cd3d745c663c697e446695ebb8e1 Mon Sep 17 00:00:00 2001
From: Camelia Groza <camelia.groza@nxp.com>
Date: Wed, 8 Jan 2020 18:41:33 +0200
Subject: [PATCH] sdk_dpaa: ceetm: fix recursive dependencies
Due to dependencies between the fsl_ceetm and fsl_dpa modules, remove
the module support for the ceetm driver and integrate it into the main
DPAA Ethernet driver.
The registration of the CEETM Qdisc was the only operation done at
module init. Pass the management of the Qdisc register and unregister
operations to the loading and unloading of the DPAA driver.
