b5ec750ebb marvell: oak: Fix build for Linux v5.14 
The functions eth_hw_addr_set() and dev_addr_mod() do not exist for
Linux v5.14 and so compiling the marvell oak driver fails for Linux
v5.14. Fix this by calling memcpy() instead of eth_hw_addr_set() and
dev_addr_mod() for Linux v5.14. Note that both eth_hw_addr_set() and
dev_addr_mod() internally call memcpy() and so this is equivalent.

2172c01a6d ethernet: Get VM IRQ config sequence from nvidia,vm-irq-id 
Ethernet driver expect the VM IRQ configuration. The VM IRQ
is provided with the property "interrupt" which have multiple
VM irq numbers and their configurations via the vm irq
configuration node which is referred by property
"nvidia,vm-irq-config".

The vm irq configuration node have the configuration of
all VM IRQ and each configuration is separated with the
child node like below.

ethernet@6800000 {
	nvidia,vm-irq-config = <&mgbe_vm_irq_config>;
}

	mgbe_vm_irq_config: mgbe-vm-irq-config {
		nvidia,num-vm-irqs = <5>;
		vm_irq1 {
			nvidia,num-vm-channels = <2>;
			nvidia,vm-channels = <0 1>;
			nvidia,vm-num = <0>;
                        nvidia,vm-irq-id = <0>;

		};
		vm_irq2 {
			nvidia,num-vm-channels = <2>;
			nvidia,vm-channels = <2 3>;
			nvidia,vm-num = <1>;
                        nvidia,vm-irq-id = <1>;
		};
		vm_irq3 {
			nvidia,num-vm-channels = <2>;
			nvidia,vm-channels = <4 5>;
			nvidia,vm-num = <2>;
                        nvidia,vm-irq-id = <2>;
		};
		vm_irq4 {
			nvidia,num-vm-channels = <2>;
			nvidia,vm-channels = <6 7>;
			nvidia,vm-num = <3>;
                        nvidia,vm-irq-id = <3>;
		};
		vm_irq5 {
			nvidia,num-vm-channels = <2>;
			nvidia,vm-channels = <8 9>;
			nvidia,vm-num = <4>;
                        nvidia,vm-irq-id = <4>;
		};
	};
};

The child 1(vm_irq1) is link with the VM IRQ  1 listed in
interrupt property, next child which is vm_irq2 is link
with the 2nd VM irq. So, the order of VM configuration
child must be in same order as VM IRQ provided in the
property interrupt.

If the irq configuration order i..e child order is not
matching with VM irq number then there is interrupt issue.

Now, if the VM IRQ config child nodes are provided in base
DT file in same order then the ethernet works fine.
But when applying via overlay, it does not work.
This is because of overlay technique. The overlay logic is
such that it iterates all child node in overlay and
apply the child as first child of target node.
Hence the child sequence provided in overlay fragment
is applied in reverse order in target node. This causes
the irq configuration order not matching with VM IRQs.

To address the overlay issue, read the sequence of
interrupt in property "interrupt" from the newly added property
"nvidia,vm-irq-id" of each child. This way child node
sequence does not matter, and sequence is identified
by property.

354ef0dbe0 drivers: Use runtime debugfs check 
When kernel command line debugfs=off is specified instead of
disabling CONFIG_DEBUG_FS in defconfig to disable Debug-FS,
debugfs functions like debugfs_create_dir will fail.

Use function debugfs_initialized() to check if debugfs
functionality is enabled before calling any debugfs functions.

This allows us to by-pass debugfs initialization if debugfs
is not enabled.

99acf2912b nvethernet: add lane bringup restart callback 
Issue: In the current scenrio, when the remote
interface is brought down and up. There is no way
of getting the link up again with the remote device
which in turn fails the data transfers even though
interface from other end is brought up.

Fix: When interface is gone down on the other side,
MAC receives local faults and in this scenario
no data should be sent to MAC, so disable network
queues and initiate the lane bring up process for
monitoring the link status. Once the link is up,
re enable the network queues for data transfers.

Also added support for enabling driver logs using
msglvl of ethtool
