82ff7a196d mlxsw: spectrum_fid: Split a helper out of mlxsw_sp_fid_flood_table_mid()
In future patches, for CFF flood mode support, we will need a way to
determine a PGT base dynamically, as an op. Therefore, for symmetry,
split out a helper, mlxsw_sp_fid_pgt_base_ctl(), that determines a PGT base
in the controlled mode as well.

Now that the helper is available, use it in mlxsw_sp_fid_flood_table_init()
which currently invokes the FID->MID helper to that end.

ab68bd743a mlxsw: spectrum_fid: Rename FID ops, families, arrays
Currently, mlxsw always uses a "controlled" flood mode on all Nvidia
Spectrum generations. The following patches will however introduce a
possibility to run a "CFF" (for Compressed FID Flooding) mode on newer
machines, if the FW supports it.

To reflect that, label all FID ops, FID families and FID family arrays with
a _ctl suffix. This will make it clearer what is what when the CFF families
are introduced in later patches.

Keep the dummy family intact. Since the dummy family has no flood tables
in either CTL or CFF mode, there are no flood-mode-specific callbacks.

Additionally, add a remark at two fields that they are only relevant when
flood mode is not CFF.

01de00f439 mlxsw: spectrum_fid: Privatize FID families
Currently, mlxsw always uses a "controlled" flood mode on all Nvidia
Spectrum generations. The following patches will however introduce a
possibility to run a "CFF" (for Compressed FID Flooding) mode on newer
machines, if the FW supports it.

Several operations will differ between how they need to be done in
controlled mode vs. CFF mode. Thus the per-FID-family ops will differ
between controlled and CFF, thus the FID family array as such will
differ depending on whether the mode negotiated with FW is controlled
or CFF.

The simple approach of having several globally visible arrays for
spectrum.c to statically choose from no longer works. Instead privatize all
FID initialization and finalization logic, and expose it as ops instead.

7edce370d8 net: phy: aquantia: drop wrong endianness conversion for addr and CRC
On further testing on BE target with kernel test robot, it was notice
that the endianness conversion for addr and CRC in fw_load_memory was
wrong.

Drop the cpu_to_le32 conversion for addr load as it's not needed.

Use get_unaligned_le32 instead of get_unaligned for FW data word load to
correctly convert data in the correct order to follow system endian.

Also drop the cpu_to_be32 for CRC calculation as it's wrong and would
cause different CRC on BE system.
The loaded word is swapped internally and MAILBOX calculates the CRC on
the swapped word. To correctly calculate the CRC to be later matched
with the one from MAILBOX, use an u8 struct and swap the word there to
keep the same order on both LE and BE for crc_ccitt_false function.
Also add additional comments on how the CRC verification for the loaded
section works.

CRC is calculated as we load the section and verified with the MAILBOX
only after the entire section is loaded to skip additional slowdown by
loop the section data again.

The Marvell switches are lacking DT bindings.

I need proper schema checking to add LED support to the
Marvell switch. Just how it is, it can't go on like this.

Some Device Tree fixes are included in the series, these
remove the major and most annoying warnings fallout noise:
some warnings remain, and these are of more serious nature,
such as missing phy-mode. They can be applied individually,
or to the networking tree with the rest of the patches.

Thanks to Andrew Lunn, Vladimir Oltean and Russell King
for excellent review and feedback!

This latest version employs special compatibles in the
odd ABI device trees.

a6e44f3028 dt-bindings: net: mvusb: Fix up DSA example
When adding a proper schema for the Marvell mx88e6xxx switch,

  is a required property
  from schema $id: http://devicetree.org/schemas/net/dsa/marvell,mv88e6xxx.yaml#

Fix this up by extending the example with those properties in
the ports node.

While we are at it, rename "ports" to "ethernet-ports" and rename
"switch" to "ethernet-switch" as this is recommended practice.

ynl-regen -f doesn't make us rebuild half of the kernel, if there
are no actual changes in any generated code.

When ynl-gen-c is called by make, however, we're better off trusting
make's tracking and overwrite the file. Otherwise if output is identical
we won't update file timestamps and make will retry code gen on every

2f58148c41 net: dsa: microchip: ksz8: Add function to configure ports with integrated PHYs
This patch introduces the function 'ksz8_phy_port_link_up' to the
Microchip KSZ8xxx driver. This function is responsible for setting up
flow control and duplex settings for the ports that are integrated with
PHYs.

The KSZ8795 switch supports asymmetric pause control, which can't be
fully utilized since a single bit controls both RX and TX pause. Despite
this, the flow control can be adjusted based on the auto-negotiation
process, taking into account the capabilities of both link partners.

On the other hand, the KSZ8873's PORT_FORCE_FLOW_CTRL bit can be set by
the hardware bootstrap, which ignores the auto-negotiation result.
Therefore, even in auto-negotiation mode, we need to ensure that this
bit is correctly set.

When auto-negotiation isn't in use, we enforce symmetric pause control
for the KSZ8795 switch.

Please note, forcing flow control disable on a port while still
advertising pause support isn't possible. While this scenario
might not be practical or desired, it's important to be aware of this
limitation when working with the KSZ8873 and similar devices.

8ae980d241 gve: Deprecate adminq_pfn for pci revision 0x1.
adminq_pfn assumes a page size of 4k, causing this mechanism to break in
kernels compiled with different page sizes. A new PCI device revision was
needed for the device to be able to communicate with the driver how to
set up the admin queue prior to having access to the admin queue.

cd04b44bf0 r8169: remove multicast filter limit
Once upon a time, when r8169 was new, the multicast filter limit code
was copied from RTL8139 driver. There the filter limit is even
user-configurable.
The filtering is hash-based and we don't have perfect filtering.
Actually the mc filtering on RTL8125 still seems to be the same
as used on 8390/NE2000. So it's not clear to me which benefit it
should bring when switching to all-multi mode once a certain number
of filter bits is set. More the opposite: Filtering out at least
some unwanted mc traffic is better than no filtering.
Also the available chip documentation doesn't mention any restriction.
Therefore remove the filter limit.

a379972973 Merge branch 'net-page_pool-add-netlink-based-introspection'
Jakub Kicinski says:

====================
net: page_pool: add netlink-based introspection

We recently started to deploy newer kernels / drivers at Meta,
making significant use of page pools for the first time.
We immediately run into page pool leaks both real and false positive
warnings. As Eric pointed out/predicted there's no guarantee that
applications will read / close their sockets so a page pool page
may be stuck in a socket (but not leaked) forever. This happens
a lot in our fleet. Most of these are obviously due to application
bugs but we should not be printing kernel warnings due to minor
application resource leaks.

Conversely the page pool memory may get leaked at runtime, and
we have no way to detect / track that, unless someone reconfigures
the NIC and destroys the page pools which leaked the pages.

The solution presented here is to expose the memory use of page
pools via netlink. This allows for continuous monitoring of memory
used by page pools, regardless if they were destroyed or not.
Sample in patch 15 can print the memory use and recycling
efficiency:

$ ./page-pool
    eth0[2]	page pools: 10 (zombies: 0)
		refs: 41984 bytes: 171966464 (refs: 0 bytes: 0)
		recycling: 90.3% (alloc: 656:397681 recycle: 89652:270201)

v4:
 - use dev_net(netdev)->loopback_dev
 - extend inflight doc
v3: https://lore.kernel.org/all/20231122034420.1158898-1-kuba@kernel.org/
 - ID is still here, can't decide if it matters
 - rename destroyed -> detach-time, good enough?
 - fix build for netsec
v2: https://lore.kernel.org/r/20231121000048.789613-1-kuba@kernel.org
 - hopefully fix build with PAGE_POOL=n
v1: https://lore.kernel.org/all/20231024160220.3973311-1-kuba@kernel.org/
 - The main change compared to the RFC is that the API now exposes
   outstanding references and byte counts even for "live" page pools.
   The warning is no longer printed if page pool is accessible via netlink.

be0096676e net: page_pool: mute the periodic warning for visible page pools
Mute the periodic "stalled pool shutdown" warning if the page pool
is visible to user space. Rolling out a driver using page pools
to just a few hundred hosts at Meta surfaces applications which
fail to reap their broken sockets. Obviously it's best if the
applications are fixed, but we don't generally print warnings
for application resource leaks. Admins can now depend on the
netlink interface for getting page pool info to detect buggy
apps.

While at it throw in the ID of the pool into the message,
in rare cases (pools from destroyed netns) this will make
finding the pool with a debugger easier.

Link the page pools with netdevs. This needs to be netns compatible
so we have two options. Either we record the pools per netns and
have to worry about moving them as the netdev gets moved.
Or we record them directly on the netdev so they move with the netdev
without any extra work.

Implement the latter option. Since pools may outlast netdev we need
a place to store orphans. In time honored tradition use loopback
for this purpose.
