RXFH is all this driver supports in RXNFC so old callbacks are

The E825-C hardware has a slightly different register layout for register
19 of the Clock Generation Unit and TSPLL. The fbdiv_intgr value can be 10
bits wide.
Additionally, most of the fields that were in register 24 are made
available in register 23 instead. The programming logic already has a
corrected definition for register 23, but it incorrectly still used the
8-bit definition of fbdiv_intgr. This results in truncating some of the
values of fbdiv_intgr, including the value used for the 156.25MHz signal.
The driver only used register 24 to obtain the enable status, which we
should read from register 23. This results in an incorrect output for the
log messages, but does not change any functionality besides
disabled-by-default dynamic debug messages.
Fix the register definitions, and adjust the code to properly reflect the
enable/disable status in the log messages.

libeth: add libeth_xdp helper lib
Alexander Lobakin says:
Time to add XDP helpers infra to libeth to greatly simplify adding
XDP to idpf and iavf, as well as improve and extend XDP in ice and
i40e. Any vendor is free to reuse helpers. If this happens, I'm fine
with moving the folder of out intel/.
The helpers greatly simplify building xdp_buff, running a prog,
handling the verdict, implement XDP_TX, .ndo_xdp_xmit, XDP buffer
completion. Same applies to XSk (with XSk xmit instead of
.ndo_xdp_xmit, plus stuff like XSk wakeup).
They are entirely generic with no HW definitions or assumptions.
HW-specific stuff like parsing Rx desc / filling Tx desc is passed
from the driver as inline callbacks.
For now, key assumptions that optimize performance / avoid code
bloat, but might not fit every driver in driver/net/:
* netmem holding the buffers are always order-0;
* driver has separate XDP Tx queues, doesn't use stack queues for
that. For best efficiency, you may want to have nr_cpu_ids XDP
queues, but less (queue sharing) is also supported;
* XDP Tx queues are interrupt-less and use "lazy" cleaning only
when there are less than 1/4 free Tx descriptors of the queue
size;
* main target platforms are 64-bit, although 32-bit is also fully
supported, but the code might be not as optimized for them.
Library code already supports multi-buffer for all kinds of Tx and
both header split and no split for Rx and Tx. Frags can come from
devmem/io_uring etc., direct `struct page *` is used only for header
buffers for which it's always true.
Drivers are free to pass their own Rx hints and XSK xmit hints ops.
XDP_TX and ndo_xdp_xmit use onstack bulk for the frames to be sent
and send them by batches of 16 buffers. This eats ~280 bytes on the
stack, but gives good boosts and allow to greatly optimize the main
sending function leaving it without any error/exception paths.
XSk xmit fills Tx descriptors in the loop unrolled by 8. This was
proven to improve perf on ice and i40e. XDP_TX and ndo_xdp_xmit
doesn't use unrolling as I wasn't able to get any improvements in
those scenenarios from this, while +1 Kb for their sending functions
for nothing doesn't sound reasonable.
XSk wakeup, instead of traditionally used "SW interrupts" provided
by NICs, uses IPI to schedule NAPI on the CPU corresponding to the
given queue pair. It gives better control over CPU distribution and
in general performs way better than "SW interrupts", plus allows us
to not pass any HW-specific callbacks there.
The code is built the way that all callbacks passed from drivers
get inlined; in general, most of hotpath gets inlined. Everything
slow/exception lands to .c files in the libeth folder, doesn't
create copies in the drivers themselves and doesn't overloat
hotpath.
Sure, inlining means that hotpath will be compiled into every driver
that uses the lib, but the core code is written in one place, so no
copying of bugs happens. Fixed once -- works everywhere.
The last commit might look like sorta hack, but it gives really good
boosts and decreases object code size, plus there are checks that
all those wider accesses are fully safe, so I don't feel anything
bad about it.
An example of using libeth_xdp can be found either on my GitHub or
on the mailing lists here ("XDP for idpf"). Macros for building
driver XDP functions lead to that some implementations (XDP_TX,
ndo_xdp_xmit etc.) consist of really only a few lines.
* '200GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:

The bulk of the work is done in mlx5e_queue_mem_alloc, where we allocate
and create the new channel resources, similar to
mlx5e_safe_switch_params, but here we do it for a single channel using
existing params, sort of a clone channel.
To swap the old channel with the new one, we deactivate and close the
old channel then replace it with the new one, since the swap procedure
doesn't fail in mlx5, we do it all in one place (mlx5e_queue_start).

On netdev_rx_queue_restart, a special type of page pool maybe expected.
In this patch declare support for UNREADABLE netmem iov pages in the
pool params only when header data split shampo RQ mode is enabled, also
set the queue index in the page pool params struct.
Shampo mode requirement: Without header split rx needs to peek at the data,
we can't do UNREADABLE_NETMEM.
The patch also enables the use of a separate page pool for headers when
a memory provider is installed for the queue, otherwise the same common
page pool continues to be used.

Locally-generated MC packets have so far not been subject to MC routing.
Instead an MC-enabled installation would maintain the MC routing tables,
and separately from that the list of interfaces to send packets to as part
of the VXLAN FDB and MDB.
In a previous patch, a ip_mr_output() and ip6_mr_output() routines were
added for IPv4 and IPv6. All locally generated MC traffic is now passed
through these functions. For reasons of backward compatibility, an SKB
(IPCB / IP6CB) flag guards the actual MC routing.
This patch adds logic to set the flag, and the UAPI to enable the behavior.

iptunnel_xmit() erases the contents of the SKB control block. In order to
be able to set particular IPCB flags on the SKB, add a corresponding
parameter, and propagate it to udp_tunnel_xmit_skb() as well.
In one of the following patches, VXLAN driver will use this facility to
mark packets as subject to IP multicast routing.

Add an integer return value to mcp251x_write_bits() and use it to
propagate the one returned by mcp251x_spi_write(). Return that value on
error in the request() GPIO callback.

In gve_adminq_issue_cmd(), return -EINVAL instead of 0 when an unknown
admin queue command opcode is encountered.
This prevents the function from silently succeeding on invalid input
and prevents undefined behavior by ensuring the function fails gracefully
when an unrecognized opcode is provided.
These changes improve error handling.

- Correct spelling and improves the clarity of comments
"confiugration" -> "configuration"
"spilt" -> "split"
"It if is 0" -> "If it is 0"
"DQ" -> "DQO" (correct abbreviation)
- Clarify BIT(0) flag usage in gve_get_priv_flags()
- Replaced hardcoded array size with GVE_NUM_PTYPES
for clarity and maintainability.
These changes are purely cosmetic and do not affect functionality.

According to the datasheet, BCM5325 uses B53_PD_MODE_CTRL_25 register to
disable clocking to individual PHYs.
Only ports 1-4 can be enabled or disabled and the datasheet is explicit
about not toggling BIT(0) since it disables the PLL power and the switch.

BCM5325 doesn't implement GMII_PORT_OVERRIDE_CTRL register so we should
avoid reading or writing it.
PORT_OVERRIDE_RX_FLOW and PORT_OVERRIDE_TX_FLOW aren't defined on BCM5325
and we should use PORT_OVERRIDE_LP_FLOW_25 instead.
