8c7d9510f2 nvethernet: support filter based dma routing API
Updated IOCTL path to not get impacted with new API
change. OSI call should be done with correct parameters
1) dma_routing_enable
2) dma_chan and
3) addr_mask (for L2 filtering) to support new IOCTL
4) src_dest (for L2 filtering) to support new IOCTL

Included logic for User priority based RxQ selection. We can have DT
entry "nvidia,rx_queue_prio" to configure this setting
i.e. for valid following Queue mapping

Priorities 6,3 to Queue 3
Priorities 4,5 to Queue 2
Priority 0 to Queue 1 and
Priority 1 to Queue 0.
setting will be nvidia,rx-queue-prio = <0x2 0x1 0x30 0x48>;

If static channel selection, i.e. RXQtoDMA set with value 0x03020100,
	Priorities 6,3 to Queue 3 to chan 3
	Priorities 4,5 to Queue 2 to chan 2
	Priority 0 to Queue 1 to chan 1 and
	Priority 1 to Queue 0 to chan 0
else if DCS(dma channel selection) enabled
	channel will be selected based on filter rules.

Included logic to take input from User On DCS enable or disable. User can
update dt entry "nvidia,dcs-enable", for dcs enable disable for all queue.
i.e nvidia,dcs-enable = <0x1> will enable DCS for all queue.
