+	default y
+	---help---
+	  The Offline Parsing / Host Command ports (short: OH ports, of Offline ports) provide
+	  most of the functionality of the regular, online ports, except they receive their
+	  frames from a core or an accelerator on the SoC, via QMan frame queues,
+	  rather than directly from the network.
+	  Offline ports are configured via PCD (Parse-Classify-Distribute) schemes, just like
+	  any online FMan port. They deliver the processed frames to frame queues, according
+	  to the applied PCD configurations.
+
+	  Choosing this feature will not impact the functionality and/or performance of the system,
+	  so it is safe to have it.

+	  - DPAA Shared MAC driver
+	  - DPAA MAC-less driver
+	  - DPAA Proxy initialization driver (for USDPAA)
+	  Select this to also build the advanced drivers.
+

+	  Optimize the DPAA Ethernet driver throughput for large frames
+	  termination traffic (e.g. 4K and above).
+	  NOTE: This option can only be used if FSL_FM_MAX_FRAME_SIZE
+	  is set to 9600 bytes.
+	  Using this option in combination with small frames increases
+	  significantly the driver's memory footprint and may even deplete
+	  the system memory.
+	  This option is not available on LS1043.

+	---help---
+	  The DPAA-Ethernet driver defines a ndo_select_queue() callback for optimal selection
+	  of the egress FQ. That will override the XPS support for this netdevice.
+	  If for whatever reason you want to be in control of the egress FQ-to-CPU selection and mapping,
+	  or simply don't want to use the driver's ndo_select_queue() callback, then unselect this
+	  and use the standard XPS support instead.
+

+	int "Maximum nuber of buffers in private bpool"
+	depends on FSL_SDK_DPAA_ETH
+	range 64 2048
+	default "128"
+	---help---
+	  The maximum number of buffers to be by default allocated in the DPAA-Ethernet private port's
+	  buffer pool. One needn't normally modify this, as it has probably been tuned for performance
+	  already. This cannot be lower than DPAA_ETH_REFILL_THRESHOLD.
+
+config FSL_DPAA_ETH_REFILL_THRESHOLD
+	int "Private bpool refill threshold"
+	depends on FSL_SDK_DPAA_ETH
+	range 32 FSL_DPAA_ETH_MAX_BUF_COUNT
+	default "80"
+	---help---
+	  The DPAA-Ethernet driver will start replenishing buffer pools whose count
+	  falls below this threshold. This must be related to DPAA_ETH_MAX_BUF_COUNT. One needn't normally
+	  modify this value unless one has very specific performance reasons.
+
+config FSL_DPAA_CS_THRESHOLD_1G
+	hex "Egress congestion threshold on 1G ports"
+	depends on FSL_SDK_DPAA_ETH
+	range 0x1000 0x10000000
+	default "0x06000000"
+	---help---
+	  The size in bytes of the egress Congestion State notification threshold on 1G ports.
+	  The 1G dTSECs can quite easily be flooded by cores doing Tx in a tight loop
+	  (e.g. by sending UDP datagrams at "while(1) speed"),
+	  and the larger the frame size, the more acute the problem.
+	  So we have to find a balance between these factors:
+	       - avoiding the device staying congested for a prolonged time (risking
+                 the netdev watchdog to fire - see also the tx_timeout module param);
+               - affecting performance of protocols such as TCP, which otherwise
+	         behave well under the congestion notification mechanism;
+	       - preventing the Tx cores from tightly-looping (as if the congestion
+	         threshold was too low to be effective);
+	       - running out of memory if the CS threshold is set too high.
+
+config FSL_DPAA_CS_THRESHOLD_10G

+	depends on FSL_SDK_DPAA_ETH
+	default "0x10000000"
+	---help---
+	  The size in bytes of the ingress tail-drop threshold on FMan ports.
+	  Traffic piling up above this value will be rejected by QMan and discarded by FMan.
+
+config FSL_DPAA_ETH_DEBUGFS
+	bool "DPAA Ethernet debugfs interface"
+	depends on DEBUG_FS && FSL_SDK_DPAA_ETH
+	default y
+	---help---
+	  This option compiles debugfs code for the DPAA Ethernet driver.
+
+config FSL_DPAA_ETH_DEBUG
+	bool "DPAA Ethernet Debug Support"
+	depends on FSL_SDK_DPAA_ETH
+	default n
+	---help---
+	  This option compiles debug code for the DPAA Ethernet driver.
+
+config FSL_DPAA_DBG_LOOP
+	bool "DPAA Ethernet Debug loopback"
+	depends on FSL_DPAA_ETH_DEBUGFS && FSL_DPAA_ETH_USE_NDO_SELECT_QUEUE
+	default n
+	---help---
+	  This option allows to divert all received traffic on a certain interface A towards a
+	  selected interface B. This option is used to benchmark the HW + Ethernet driver in
+	  isolation from the Linux networking stack. The loops are controlled by debugfs entries,
+	  one for each interface. By default all loops are disabled (target value is -1). I.e. to
+	  change the loop setting for interface 4 and divert all received traffic to interface 5
+	  write Tx interface number in the receive interface debugfs file:
+		# cat /sys/kernel/debug/powerpc/fsl_dpa/eth4_loop
+			4->-1
+		# echo 5 > /sys/kernel/debug/powerpc/fsl_dpa/eth4_loop
