Instead of just looking for a hw_config with matching rate only it sounds
better to try to find the best matching configuration.
If we have multiple hw_configurations with the same rate, but each with
different format for example then we have been picking the first config
with the matching rate, which can be a problem and it wil depend on how
the configs are ordered.
Instead we should be trying to find the best match out of the configs
1. rate + format + channels are matching
2. rate + format are matching
3. rate matching

netpoll: Code organization improvements
The netpoll_setup() function has grown complex over time, mixing
different error handling and concerns like carrier waiting, IPv4 address
retrieval, and IPv6 address retrieval all within a single function,
which is huge (127 LoC).
This patch series refactors the netpoll_setup() function to improve code
organization and readability by extracting logical blocks into dedicated
helper functions. netpoll_setup() length is reduced to 72 LoC.
This series breaks down these responsibilities into focused helper
functions.
The changes are purely structural with no functional modifications.
This changes were tested with the netconsole tests and the netpoll
selftest (WIP)[1]

appropriate error handling when IPv6 is not supported or no

This is what happens for regular neighbour entries.
So lets fix this by:
- storing in proxy entries the fact that it was added as NUD_PERMANENT
- not removing NUD_PERMANENT proxy entries when the carrier goes down

The doorbell physical address is used by the RDMA driver to map
doorbell pages of the device to user-mode applications through RDMA

the device is in VF mode. With the support for PF mode implemented,

Additionally, the explicit calls to usb_autopm_get_interface() and
usb_autopm_put_interface() have been removed. These were originally
needed to manage USB power management during register accesses. However,
lan78xx_mdiobus_read() and lan78xx_mdiobus_write() already handle USB
auto power management internally, ensuring that the interface remains
active when necessary. Since there are no other direct register accesses
in these functions that require explicit power management handling, the
extra calls have become redundant and are no longer needed.

The EVENT_LINK_RESET macro currently triggers deferred work after a PHY
interrupt. Prior to PHYLINK conversion, this work included reconfiguring
the MAC and PHY, effectively performing a 'link reset'.
However, after porting the driver to the PHYLINK framework, the logic
associated with this event now solely handles the acknowledgment of
the PHY interrupt. The MAC and PHY reconfiguration is now managed by
PHYLINK's dedicated callbacks.
To accurately reflect its current, narrowed functionality, rename
EVENT_LINK_RESET to EVENT_PHY_INT_ACK.

Convert the LAN78xx USB Ethernet driver to use the PHYLINK framework for
managing PHY and MAC interactions. This improves consistency with other
network drivers, simplifies pause frame handling, and enables cleaner
suspend/resume support.
Key changes:
- Replace all PHYLIB-based logic with PHYLINK equivalents:
- Replace phy_connect()/phy_disconnect() with phylink_connect_phy()
- Replace phy_start()/phy_stop() with phylink_start()/phylink_stop()
- Replace pauseparam handling with phylink_ethtool_get/set_pauseparam()
- Introduce lan78xx_phylink_setup() to configure PHYLINK
- Add phylink MAC operations:
- lan78xx_mac_config()
- lan78xx_mac_link_up()
- lan78xx_mac_link_down()
- Remove legacy link state handling:
- lan78xx_link_status_change()
- lan78xx_link_reset()
- Handle fixed-link fallback for LAN7801 using phylink_set_fixed_link()
- Replace deprecated flow control handling with phylink-managed logic
Power management:
- Switch suspend/resume paths to use phylink_suspend()/phylink_resume()
- Ensure proper use of rtnl_lock() where required
- Note: full runtime testing of power management is currently limited
due to hardware setup constraints
Note: Conversion of EEE (Energy Efficient Ethernet) handling to the
PHYLINK-managed API will be done in a follow-up patch. For now, the
legacy EEE enable logic is preserved in mac_link_up().

We can avoid open-coding the loop construct which counts firmware child
nodes with a specific name by using the newly added
device_get_named_child_node_count().
The gianfar driver has such open-coded loop. Replace it with the
device_get_child_node_count_named().

There are the functions fec_enet_rx_queue() and fec_enet_tx_queue(),
one for handling the RX queue the other one handles the TX queue.
However they don't have the same signature. Align fec_enet_rx_queue()
argument order with fec_enet_tx_queue() to make code more readable.

====================
net: stmmac: loongson1: cleanups
A couple of patches to cleanup loongson1. First, introducing a match
data struct to allow the per-match data to be extended beyond the init
function pointer, and then adding a setup method to allow the resource
base address to be translated to the MAC index at probe time rather
than repeatedly in the setup function.

ls1b_dwmac_syscon_init() was getting the stmmac iomem resource to detect
which GMAC block is being used. Move this to a separate setup() function
that only runs at probe time, so it can sensibly behave with an
unrecognised resource adress. Use this to set a MAC index (id) which is
then used in place of testing the base address.

going through a hub), a Type-A USB 2.0 port (also going through a hub),
a Type-C DC input port that has absolutely no USB data connection and a
Type-C port with USB3.2 Gen1x1 that's also the maskrom programming port.
Enable these ports, and set the device role to be host for the host
ports.
The data capable Type-C USB port uses a fusb302 for data role switching.
