+Subject: [PATCH] sdk_dpaa: ceetm: add independent CEETM congestion thresholds
+
+Configure the CEETM egress congestion thresholds independently from the
+default Ethernet driver's Work Queues. Allow the user to edit the
+thresholds through menuconfig.

++	  The threshold needs to be configured keeping in mind the following factors:

++	       when a small shaping rate is configured. This will cause buffer pool depletion
++	       or out of memory errors. This in turn will cause frame loss on RX;
++	       - A threshold too small will cause unnecessary frame loss by entering
