20e4a2fb7a nvethernet: Call netif_carrier_on/off based on PHY link 
Issue: When configuring loopback mode, netif_carrier_on/off
       APIs are directly used i.e, netif_carrier_on when
       loopback mode enabled, netif_carrier_off when
       loopback mode is disabled. If anyone enables/disables
       loopback mode when link is alreay up, then link is
       not restored. Stack is not sending packets due
       to netif_carrier_off.
Fix:   Check PHY link status before calling netif_carrier_*
       APIs. If link is up, then PHY framework would have
       already invoked these APIs.

ae038d9360 nvethernet: Enable slot function support 
Issue:
Data packets sent via EQOS hardware are not
following any packet gaping. The AVB use-cases
have different timing requirements for class A
data packets. For example, the time difference
between two class A data packets are supposed
to be 125 microseconds for audio data
of frequency 48 kHz.

Fix:
Enable slot function support to schedule the data
fetching from the system memory by the DMA.
This feature is useful when the source AV data
needs to be transmitted at specific intervals.

filtering is not supported in SW.

not configured for L3/L4 filtering.

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.
