Implement mqprio qdisc support by mapping traffic classes to
different hardware enqueue priorities. The maximum number of
supported traffic classes is an attribute of each DPNI object.
The traffic classes map to hardware priorities from highest (0)
to lowest (highest prio number). The skb priority information
received from the stack is used to select the hardware Tx queue
on which to enqueue the frame.

DPNI objects can have multiple traffic classes, as reflected by
the num_tc attribute. Until now we ignored its value and only
used traffic class 0.
This patch adds support for multiple Tx traffic classes; we have
num_queues x num_tcs hardware queues available for each interface.

When TCP stream gets out of sync (driver stops receiving skbs
with expected TCP sequence numbers) request a TX resync from
the kernel.
We try to distinguish retransmissions from missed transmissions
by comparing the sequence number to expected - if it's further
than the expected one - we probably missed packets.

Some control messages must be sent from atomic context. The mailbox
takes sleeping locks and uses a waitqueue so add a "posted" version
of communication.
Trylock the semaphore and if that's successful kick of the device
communication. The device communication will be completed from
a workqueue, which will also release the semaphore.
If locks are taken queue the message and return. Schedule a
different workqueue to take the semaphore and run the communication.
Note that the there are currently no atomic users which would actually
need the return value, so all replies to posted messages are just
freed.

TLS offload code casts record number to a u64. The buffer
should be aligned to 8 bytes, but its actually a __be64, and
the rest of the TLS code treats it as big int. Make the
offload callbacks take a byte array, drivers can make the
choice to do the ugly cast if they want to.
Prepare for copying the record number onto the stack by
defining a constant for max size of the byte array.

Based on review, `lock' is only acquired in hwbm_pool_add() which is
invoked via ->probe(), ->resume() and ->ndo_change_mtu(). Based on this
the lock can become a mutex and there is no need to disable interrupts
during the procedure.
Now that the lock is a mutex, hwbm_pool_add() no longer invokes
hwbm_pool_refill() in an atomic context so we can pass GFP_KERNEL to
hwbm_pool_refill() and remove the `gfp' argument from hwbm_pool_add().

According to the comment, the preempt_disable() statement is required
due to synchronisation in napi_alloc_frag(). The awful truth is that
local_bh_disable() is required because otherwise the NAPI poll callback
can be invoked while the open function setup buffers. This isn't
unlikely since the dpaa2 provides multiple devices.
The usage of napi_alloc_frag() has been removed in commit
27c874867c4e9 ("dpaa2-eth: Use a single page per Rx buffer")
which means that the comment is not accurate and the preempt_disable()
statement is not required.
Remove the outdated comment and the no longer required
preempt_disable().

Some CPTS instances, which can be found on KeyStone 2 1G Ethernet Switch
Subsystems, can control an external multiplexer that selects one of up to
32 clocks as time sync reference (RFTCLK) clock. This feature can be
configured through CPTS_RFTCLK_SEL register (offset: x08) in CPTS module
and can be represented as multiplexer clock.
Hence, introduce support for optional cpts-refclk-mux clock, which, once
defined will allow to select required CPTS RFTCLK by using
assigned-clock-parents DT property in board files.

Currently the axienet driver requires the use of a second devicetree
node, referenced by an axistream-connected attribute on the Ethernet
device node, which contains the resources for the AXI DMA block used by the
device. This setup is problematic for a use case we have where the Ethernet
and DMA cores are behind a PCIe to AXI bridge and the memory resources for
the nodes are injected into the platform devices using the multifunction
device subsystem - it's not easily possible for the driver to obtain the
platform-level resources from the linked device.
In order to simplify that usage model, and simplify the overall use of
this driver in general, allow for all of the resources to be kept on one
node where the resources are retrieved using platform device APIs rather
than device-tree-specific ones. The previous usage setup is still
supported if the axistream-connected attribute is specified.

This driver was previously using the parent node of the specified PHY
node as the device node to register the MDIO bus on. Andrew Lunn
pointed out this is wrong as the PHY node is potentially not even
underneath the MDIO bus for the current device instance. Find the MDIO
node explicitly by looking it up by name under the controller's device
node instead.
This could potentially break existing device trees if they don't use
"mdio" as the name for the MDIO bus, but I did not find any with various
searches and Xilinx's examples all use mdio as the name so it seems like
this should be relatively safe.
