The driver may sleep under a spinlock.
The function call path is:

kzalloc(GFP_KERNEL) --> may sleep

staging: fsl-mc: Allocate IRQ's before scanning DPRC objects
Following is the current scenario when the devices are probed:
FSL_MC Bus probe ---> dprc probe ---> dprc devices scan --->
probe devices in DPRC container ---> allocate IRQ's
In case the devices being probed in the DPRC container need the IRQ's;
probing of that device will fail.
In current scenario the devices which need IRQ's such as DPIO gets
deferred because they aren't registered when first time the probing
of these devices is done in the dprc scan.
So they are probed once IRQ's have been allocated.
In case where DPRC probing itself gets deferred, which does in case
IOMMU is enabled; all the devices in DPRC container gets probed before
IRQ's are allocated. This causes devices using IRQ's (such as DPIO)
to fail.
So having IRQ's allocated before any of the devices in the DPRC container
are probed is more legitimate.
After this patch following is the flow of execution:
FSL_MC Bus probe ---> dprc probe ---> dprc devices scan --->
allocate IRQ's ---> probe of devices in DPRC container.

staging: fsl-dpaa2/eth: Make Tx buffer alignment optional
Aligning the Tx buffers at 64B is a performance optimization
recommendation, not a hard requirement.
Make optional the alignment of Tx FD buffers, without enforcing
a reallocation in case there is not enough headroom for it.
On Rx, we keep allocating buffers with enough headroom to allow
Tx alignment of forwarded frames.

For Tx confirmed frames that have an error indication in the frame
descriptor, we look at the Frame Annotation Status field (in the

a debug message with that information.
While useful in initial development stages, it doesn't bring
enough added value to justify reserving 64B of headroom for all
Tx frames (FAS is only 8B long, but we must reserve chunks of 64B
from the hardware annotation area).
If we remove the need for FAS field from egress frames, we can
renounce hardware annotation completely, since FAS is the only
HWA field we currently use.

Commit
4b2d9fe87950 ("staging: fsl-dpaa2/eth: Extra headroom in RX
buffers") tried to avoid the performance penalty of doing skb
reallocations in the network stack for IP forwarded frames between
two DPAA2 Ethernet interfaces. This led to a (too) complicated
formula that relies on the stack's internal implementation.
Instead, it's safer and easier to just not request any guarantee
from the stack. We already double check in the driver the required
headroom size of egress frames and realloc the skb if needed, so
we don't need to add any extra code.
On forwarding between two of our own interfaces, there is no
functional change; for traffic forwarded from a different device or
generated on the core, skb realloc operations are moved from the stack
to our driver, with no visible impact on performance.

Commit
4b2d9fe87950 ("staging: fsl-dpaa2/eth: Extra headroom in RX

buffer layout, as it's not used by anyone, but fails to update the
macros for accessing hardware annotation (HWA) fields, which is
right after the SWA in the buffer headroom.
This may lead to some frame annotation status fields (e.g. indication
if L3/L4 checksum is valid) to be read incorrectly.
Turn the accessor macros into inline functions and add a bool param
to specify if SWA is present or not.
