48e0d60b07 nvethernet: PHY register read/write for fixed-link case 
ethernet@<address> {
    nvidia,mdio_address = <PHY MDIO bus address>;

    fixed-link {
	speed = <1000>;
	full-duplex;
    };
};

1. Added nvidia DT property (nvidia,mdio_address) for passing
   the PHY MDIO bus address.
2. If this property present in DT then driver calls PHY MDIO
   read/write functions directly instead of going through PHY subsystem.
3. If this property is not present – then driver PHY mdio
   read/write goes through PHY subsystem.

a955fa087a nvethernet:k5.10 Fix probe defer warning prints 
Issue
- Driver probe defer causes failed prints on kernel boot logs
  if clk/reset controller driver module is not initialized
  before nvethernet module probe.

Fix
- The probe defer is part of kernel mechanism to retry module
  initialization and hardware setup. This is not an error
  or failure for software driver.
  Only in case of probe failure, throw error logs in console

ifr_data pointer value used to carry mii_ioctl_data from
user space to kernel space. When all values are zero it
reflects the pointer value as zero and ifr_data NULL pointer
check will result in failure.

Driver should not check since ifr_data pointer value itself
represent mii_ioctl_data. So removing the NULL check for ifr_data.

- Final queue will start when a packet received with TTL=1
- TTL = 2 and 3 packets will be queued into final if those are in
sequence else those will be queued to master queue.
- When packet received with TTL = 2 then only merge process will start
- For every valid final queue merge starts by looking at the IPID
in master queue in increment order. This loop continues until
TTL = 2 found in master queue.
- Once TTL = 2 found then entire final queue will be given GRO
