a6df50dc0b staging: ccree: fix ivgen naming convention
The ivgen files were using a func naming convention which was
inconsistent (ssi vs. cc), included a long prefix (ssi_ivgen)
and often too long.

Make the code more readable by switching to a simpler, consistent naming
convention.

c163685fc8 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.

18c21467b2 staging: fsl-dpaa2/eth: Compute needed headroom per frame
For non-linear skbs we build scatter-gather frames and allocate
a new buffer for the S/G table in which we reserve the required
headroom, so the actual skb headroom size doesn't matter.

Rather than use a one-size-fits-all approach, decide when to
enforce headroom requirements on a frame by frame basis.

2b7c86eb7b staging: fsl-dpaa2/eth: Don't enable FAS on Tx
For Tx confirmed frames that have an error indication in the frame
descriptor, we look at the Frame Annotation Status field (in the
buffer headroom) for details on the root cause and then print
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.

441851b49a staging: fsl-dpaa2/eth: Don't set netdev->needed_headroom
Commit 4b2d9fe879 ("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.

54ce891779 staging: fsl-dpaa2/eth: Fix access to FAS field
Commit 4b2d9fe879 ("staging: fsl-dpaa2/eth: Extra headroom in RX
buffers") removes the software annotation (SWA) area from the 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.

Fixes: 4b2d9fe879 ("staging: fsl-dpaa2/eth: Extra headroom in RX buffers")
