A simple change to the struct ionic_queue layout removes some
unnecessary padding and saves us a cacheline in the struct
ionic_qcq layout.
struct ionic_queue {
Before: /* size: 256, cachelines: 4, members: 29 */
After: /* size: 192, cachelines: 3, members: 29 */
struct ionic_qcq {
Before: /* size: 2112, cachelines: 33, members: 23 */

Rearange a few fields for better cache use and to put the
flags field up into the first cacheline rather than the last.

Remove the idev field from ionic_queue, which saves us a
bit of space, and add it into ionic_cq where there's room
within some cacheline padding. Use this pointer rather
than doing a multi level reference from lif->ionic.

The existing ionic_rx_frags() code is a bit of a mess and can
be cleaned up by unrolling the first frag/header setup from
the loop, then reworking the do-while-loop into a for-loop. We
rename the function to a more descriptive ionic_rx_build_skb().
We also change a couple of related variable names for readability.

Make desc_info structure specific to the queue type, which
allows us to cut down the Rx and AdminQ descriptor sizes by
not including all the fields needed for the Tx desriptors.
Before:
struct ionic_desc_info {
/* size: 464, cachelines: 8, members: 6 */
After:
struct ionic_tx_desc_info {
/* size: 464, cachelines: 8, members: 6 */
struct ionic_rx_desc_info {
/* size: 224, cachelines: 4, members: 2 */

With a little simple math we don't need another struct array to
find the completion structs, so we can remove the ionic_cq_info
altogether. This doesn't really save anything in the ionic_cq
since it gets padded out to the cacheline, but it does remove
the parallel array allocation of 8 * num_descriptors, or about
8 Kbytes per queue in a default configuration.

By reworking the queue service routines to have their own
servicing loops we can remove the cb pointer from desc_info
to save another 8 bytes per descriptor,
This simplifies some of the queue handling indirection and makes
the code a little easier to follow, and keeps service code in
one place rather than jumping between code files.

Remove the struct pointers from desc_info to use less space.
Instead of pointers in every desc_info to its descriptor,
we can use the queue descriptor index to find the individual
desc, desc_info, and sgl structs in their parallel arrays.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The pause frame counters are only enabled if the "counters_en"

Intel Wired LAN Driver Updates 2024-03-04 (ice)
This series contains updates to ice driver only.
Jake changes the driver to use relative VSI index for VF VSIs as the VF
driver has no direct use of the VSI number on ice hardware. He also
reworks some Tx/Rx functions to clarify their uses, cleans up some style
issues, and utilizes kernel helper functions.
Maciej removes a redundant call to disable Tx queues on ifdown and
removes some unnecessary devm usages.

The R-Car and RZ/G2L Rx code paths were split in two separate
implementations when support for RZ/G2L was added due to the fact that
R-Car uses the extended descriptor format while RZ/G2L uses normal
descriptors. This has led to a duplication of Rx logic with the only
difference being the different Rx descriptors types used. The
implementation however neglects to take into account that extended
descriptors are normal descriptors with additional metadata at the end
to carry hardware timestamp information.
The hardware timestamp information is only consumed in the R-Car Rx
loop and all the maintenance code around the Rx ring can be shared
between the two implementations if the difference in descriptor length
is carefully considered.
This change merges the two implementations for Rx ring maintenance by
adding a method to access both types of descriptors as normal
descriptors, as this part covers all the fields needed for Rx ring
maintenance the only difference between using normal or extended
descriptor is the size of the memory region to allocate/free and the
step size between each descriptor in the ring.

To make it possible to merge the R-Car and RZ/G2L code paths move the
maximum usable size of a single Rx descriptor data slice into the
hardware information instead of using two different defines in the two
different code paths.

Remove the define describing the RZ/G2L maximum frame size and only use
the information in the hardware information struct. This will make it
easier to merge the R-Car and RZ/G2L code paths.
There is no functional change as both the define and the maximum frame
length in the hardware information is set to 8K.

The EtherAVB device requires the SKB data to be aligned to 128 bytes.
The alignment is done by allocating an skb 128 bytes larger than the
maximum frame size supported by the device and adjusting the headroom to
fit the requirement.
This code has been refactored a few times and small issues have been
added along the way. The issues are not harmful but prevent merging
parts of the Rx code which have been split in two implementations with
the addition of RZ/G2L support, a device that supports larger frame
sizes.
This change removes the need for duplicated and somewhat inaccurate
hardware alignment constrains stored in the hardware information struct
by creating a helper to handle the allocation of an skb and alignment of
an skb data.
For the R-Car class of devices the maximum frame size is 4K and each
descriptor is limited to 2K of data. The current implementation does not
support split descriptors, this limits the frame size to 2K. The
current hardware information however records the descriptor size just
under 2K due to bad understanding of the device when larger MTUs where
added.
For the RZ/G2L device the maximum frame size is 8K and each descriptor
is limited to 4K of data. The current hardware information records this
correctly, but it gets the alignment constrains wrong as just aligns it
by 128, it does not extend it by 128 bytes to allow the full frame to be
stored. This works because the RZ/G2L device supports split descriptors
and allocates each skb to 8K and aligns each 4K descriptor in this
space.

The struct member rx_max_buf_size was added before split descriptor
support was added. It is unclear if the value describes the full skb
frame buffer or the data descriptor buffer which can be combined into a
single skb.
Rename it to make it clear it referees to the maximum frame size and can
cover multiple descriptors.

The Rx ring can either be made up of normal or extended descriptors, not
a mix of the two at the same time. Make this explicit by grouping the
two variables in a rx_ring union.
The extension of the storage for more than one queue of normal
descriptors from a single to NUM_RX_QUEUE queues have no practical
effect. But aids in making the code readable as the code that uses it
already piggyback on other members of struct ravb_private that are
arrays of max length NUM_RX_QUEUE, e.g. rx_desc_dma. This will also make
further refactoring easier.
While at it, rename the normal descriptor Rx ring to make it clear it's
not strictly related to the GbEthernet E-MAC IP found in RZ/G2L, normal
descriptors could be used on R-Car SoCs too.

====================
idpf: refactor virtchnl messages
Alan Brady says:
The motivation for this series has two primary goals. We want to enable
support of multiple simultaneous messages and make the channel more
robust. The way it works right now, the driver can only send and receive
a single message at a time and if something goes really wrong, it can
lead to data corruption and strange bugs.
To start the series, we introduce an idpf_virtchnl.h file. This reduces
the burden on idpf.h which is overloaded with struct and function
declarations.
The conversion works by conceptualizing a send and receive as a
"virtchnl transaction" (idpf_vc_xn) and introducing a "transaction
manager" (idpf_vc_xn_manager). The vcxn_mngr will init a ring of
transactions from which the driver will pop from a bitmap of free
transactions to track in-flight messages. Instead of needing to handle a
complicated send/recv for every a message, the driver now just needs to
fill out a xn_params struct and hand it over to idpf_vc_xn_exec which
will take care of all the messy bits. Once a message is sent and
receives a reply, we leverage the completion API to signal the received
buffer is ready to be used (assuming success, or an error code
otherwise).
At a low-level, this implements the "sw cookie" field of the virtchnl
message descriptor to enable this. We have 16 bits we can put whatever
we want and the recipient is required to apply the same cookie to the
reply for that message. We use the first 8 bits as an index into the
array of transactions to enable fast lookups and we use the second 8
bits as a salt to make sure each cookie is unique for that message. As
transactions are received in arbitrary order, it's possible to reuse a
transaction index and the salt guards against index conflicts to make
certain the lookup is correct. As a primitive example, say index 1 is
used with salt 1. The message times out without receiving a reply so
index 1 is renewed to be ready for a new transaction, we report the
timeout, and send the message again. Since index 1 is free to be used
again now, index 1 is again sent but now salt is 2. This time we do get
a reply, however it could be that the reply is _actually_ for the
previous send index 1 with salt 1. Without the salt we would have no
way of knowing for sure if it's the correct reply, but with we will know
for certain.
Through this conversion we also get several other benefits. We can now
more appropriately handle asynchronously sent messages by providing
space for a callback to be defined. This notably allows us to handle MAC
filter failures better; previously we could potentially have stale,
failed filters in our list, which shouldn't really have a major impact
but is obviously not correct. I also managed to remove fairly
significant more lines than I added which is a win in my book.
Additionally, this converts some variables to use auto-variables where
appropriate. This makes the alloc paths much cleaner and less prone to
memory leaks. We also fix a few virtchnl related bugs while we're here.
