The hwmon temperature sensor devices is registered using a devm_hwmon
API call. The marvell_release() would then manually free the device,
not using a devm_hmon API, resulting in the device being removed
twice, leading to a crash in kernfs_find_ns() during the second
removal.
Remove the manual removal, which makes marvell_release() empty, so
remove it as well.

The bcmgenet_tx_reclaim() function is used to reclaim transmit
resources in different places within the driver. Most of them
should not affect the state of the transmit flow control.
This commit relocates the logic for waking tx queues based on
freed resources to the napi polling function where it is more
appropriate.

When using the internal PHY it must be powered up when the MII is probed
or the PHY will not be detected. Since the PHY is powered up at reset
this has not been a problem. However, when the kernel is restarted with
kexec the PHY will likely be powered down when the kernel starts so it
will not be detected and the Ethernet link will not be established.
This commit explicitly powers up the internal PHY when the GENET driver
is probed to correct this behavior.

In preparation to move the work-queue initialization to port creation
from current port_open phase. Work-queue initialization does not make
sense every time we do 'ifup/ifdown'. So moving to port creation phase.
Arp monitoring work depends on the bonding mode and that is not tied
to the port creation and can change anytime during the life after port
creation. So this restructuring allows us to move the initialization
at creation without losing the ability to arm the correct work for the
mode user has selected.

ACPI support has been added to ARM IOMMU driver in 4.10 kernel
and that has resulted in VNIC interfaces throwing translation
faults when kernel is booted with ACPI as driver was not using
DMA API. This patch fixes the issue by using DMA API which inturn
will create translation tables when IOMMU is enabled.
Also VNIC doesn't have a seperate receive buffer ring per receive
queue, so there is no 1:1 descriptor index matching between CQE_RX
and the index in buffer ring from where a buffer has been used for
DMA'ing. Unlike other NICs, here it's not possible to maintain dma
address to virt address mappings within the driver. This leaves us
no other choice but to use IOMMU's IOVA address conversion API to
get buffer's virtual address which can be given to network stack
for processing.
