Just because otx2_atomic64_add is using u64 pointer as argument
all callers has to typecast __iomem void pointers which inturn
causing sparse warnings. Fix those by changing otx2_atomic64_add
argument to void pointer.

QOS is designed to create a new send queue whenever a class
is created, ensuring proper shaping and scheduling. However,
when multiple send queues are created and deleted in a loop,
SMMU errors are observed.
This patch addresses the issue by performing an data cache sync
during the teardown of QOS send queues.

This patch adds support to AF_XDP zero copy for CN10K.
This patch specifically adds receive side support. In this approach once
a xdp program with zero copy support on a specific rx queue is enabled,
then that receive quse is disabled/detached from the existing kernel
queue and re-assigned to the umem memory.

Page pool for each rx queue enhance rx side performance
by reclaiming buffers back to each queue specific pool. DMA
mapping is done only for first allocation of buffers.
As subsequent buffers allocation avoid DMA mapping,
it results in performance improvement.

This patch registers callbacks to support HTB offload.
Below are features supported,
- supports traffic shaping on the given class by honoring rate and ceil
configuration.
- supports traffic scheduling, which prioritizes different types of
traffic based on strict priority values.
- supports the creation of leaf to inner classes such that parent node
rate limits apply to all child nodes.

Current implementation is such that the number of Send queues (SQs)
are decided on the device probe which is equal to the number of online
cpus. These SQs are allocated and deallocated in interface open and c
lose calls respectively.
This patch defines new APIs for initializing and deinitializing Send
queues dynamically and allocates more number of transmit queues for
QOS feature.
