These stats are read from MAC HW RMON counters as well as SW controlled
control from Core and DMA path.
ethtool -S <interface> is used to get statistics.
There are 3 stats
1) ether_mmc_counters: EQOS HW counters
2) ether_xtra_stat_counters: SW counters from osi/core
3) ether_xtra_dma_stat_counters: SW counters from osi/dma

Ethernet pad calibration needs to be triggered for temperature
changes in steps of 35C from -40C to 110C. In order to get
indication of current operating temperature, register a ethernet
cooling device with thermal zones defined as per above requirement.
When the temperature trips these zones, callback function is invoked
from kernel thermal framework, and ethernet driver can trigger pad
calibration.

Add dma-mask parsing in device tree for eqos
driver if IOMMU is enabled. This will allow
memory allocations from the specified address
and downwards, while device can reach every part
of physical memory through the IOMMU.
dma-mask will be remain default 32-bit mask if no
IOMMU is present since now DMA mask represents a
fundamental limit of the device.

Upstream Linux kernel commit b48b89f9c189 ("net: drop the weight
argument from netif_napi_add") removes the weight argument from the
netif_napi_add() function and this is breaking the build of a few
drivers that use this function. Fix this by updating these drivers to
use the netif_napi_add_weight() function instead for Linux v6.1.
