In preparation for the new LAG functionality implementation, there are
a couple of existing LAG elements of the capabilities struct that should
be bool instead of u8. Since we are adding a new element to this struct
that should also be a bool, fix the existing LAG u8 in this patch and
eliminate !! operators where possible.

This series will be touching on the LAG code in the ice driver,
to prevent moving or propagating casting on void pointers, clean
them up first.
This also allows for moving the variable initialization into the
variable declaration.

Support IPv6 Flow Label hashing. Use both inner and outer IPv6
header's Flow Label if both headers are detected. Flow Label
is unlike normal header fields, by enabling it user accepts
the unstable hash and possible reordering. Because of that
I think it's reasonable to hash over all Flow Labels we can
find, even tho we don't hash over all L3 addresses.

Without setting phy_mask for ax88772 mdio bus, current driver may create
at most 32 mdio phy devices with phy address range from 0x00 ~ 0x1f.
DLink DUB-E100 H/W Ver B1 is such a device. However, only one main phy
device will bind to net phy driver. This is creating issue during system
suspend/resume since phy_polling_mode() in phy_state_machine() will
directly deference member of phydev->drv for non-main phy devices. Then
NULL pointer dereference issue will occur. Due to only external phy or
internal phy is necessary, add phy_mask for ax88772 mdio bus to workarnoud
the issue.

In the past %pK was preferable to %p as it would not leak raw pointer
values into the kernel log.
Since commit ad67b74d2469 ("printk: hash addresses printed with %p")
the regular %p has been improved to avoid this issue.
Furthermore, restricted pointers ("%pK") were never meant to be used
through tracepoints. They can still unintentionally leak raw pointers or
acquire sleeping locks in atomic contexts.
Switch to the regular pointer formatting which is safer and
easier to reason about.
There are still a few users of %pK left, but these use it through seq_file,
for which its usage is safe.

The data page pool always fills the HW rx ring with pages. On arm64 with
64K pages, this will waste _at least_ 32K of memory per entry in the rx
ring.
Fix by fragmenting the pages if PAGE_SIZE > BNXT_RX_PAGE_SIZE. This
makes the data page pool the same as the header pool.
Tested with iperf3 with a small (64 entries) rx ring to encourage buffer
circulation.

When `devm_add_action_or_reset()` fails, it is due to a failed memory
allocation and will thus return `-ENOMEM`. `dev_err_probe()` doesn't do
anything when error is `-ENOMEM`. Therefore, remove the useless call to
`dev_err_probe()` when `devm_add_action_or_reset()` fails, and just
return the value instead.

and then return -EINVAL immediately to avoid waiting for the timeout when
the DMA reset fails in loongson_dwmac_fix_reset().

Back in 2017, commit 2fd260f03b6a ("PCI/AER: Remove unused .link_reset()
callback") removed .link_reset() from struct pci_error_handlers, but left
a few code comments behind which still mention it. Remove them.
The code comments in the SolarFlare Ethernet drivers point out that no
.mmio_enabled() callback is needed because the driver's .error_detected()
callback always returns PCI_ERS_RESULT_NEED_RESET, which causes
pcie_do_recovery() to skip .mmio_enabled(). That's not quite correct
because efx_io_error_detected() does return PCI_ERS_RESULT_RECOVERED under
certain conditions and then .mmio_enabled() would indeed be called if it
were implemented. Remove this misleading portion of the code comment as
well.

After a Fatal Error has been reported by a device and has been recovered
through a Secondary Bus Reset, AER updates the device's error_state to
pci_channel_io_normal before invoking its driver's ->resume() callback.
By contrast, EEH updates the error_state earlier, namely after resetting
the device and before invoking its driver's ->slot_reset() callback.
Commit c58dc575f3c8 ("powerpc/pseries: Set error_state to
pci_channel_io_normal in eeh_report_reset()") explains in great detail
that the earlier invocation is necessitated by various drivers checking
accessibility of the device with pci_channel_offline() and avoiding
accesses if it returns true. It returns true for any other error_state
than pci_channel_io_normal.
The device should be accessible already after reset, hence the reasoning
is that it's safe to update the error_state immediately afterwards.
This deviation between AER and EEH seems problematic because drivers
behave differently depending on which error recovery mechanism the
platform uses. Three drivers have gone so far as to update the
error_state themselves, presumably to work around AER's behavior.
For consistency, amend AER to update the error_state at the same recovery
steps as EEH. Drop the now unnecessary workaround from the three drivers.
Keep updating the error_state before ->resume() in case ->error_detected()
or ->mmio_enabled() return PCI_ERS_RESULT_RECOVERED, which causes
->slot_reset() to be skipped. There are drivers doing this even for Fatal
Errors, e.g. mhi_pci_error_detected().

the resume paths.

We can further simplify the driver as there is no need to track whether
the device was suspended, we only need to check whether the device is
wakeup capable in the resume method. This is because the resume method
will only be called after the suspend method.

addresses are provided through configfs, which contains newlines in

Teach netpoll_parse_ip_addr() how to ignore newlines at the end of the

* No need to check for separators. Try to parse ipv4, if it fails try
ipv6 similarly to ceph_pton()
* If ipv6 is not supported, don't call in6_pton() at all.

Users of the ixgbe driver report that after adding devlink support by
the commit a0285236ab93 ("ixgbe: add initial devlink support") their
configs got broken due to unwanted changes of interface names. It's
caused by automatic phys_port_name generation during devlink port
initialization flow.
To prevent from that set no_phys_port_name flag for ixgbe devlink ports.

It's necessary to adjust the MAC TX clock when the linkspeed changes,
but it's noted such adjustment always fails on TH1520 SoC, and reading
back from APB glue registers that control clock generation results in
garbage, causing broken link.
With some testing, it's found a clock must be ungated for access to APB
glue registers. Without any consumer, the clock is automatically
disabled during late kernel startup. Let's get and enable it if it's
described in devicetree.
For backward compatibility with older devicetrees, probing won't fail if
the APB clock isn't found. In this case, we emit a warning since the
link will break if the speed changes.

reset_gpio is claimed in mdiobus_register_device(), but it is not
released in mdiobus_unregister_device(). It is instead only
released when the whole MDIO bus is unregistered.
When a device uses the reset_gpio property, it becomes impossible
to unregister it and register it again, because the GPIO remains
claimed.
This patch resolves that issue.

TJA1103/04/20/21 support both C22 and C45 accessing methods.
The TJA11xx driver has implemented the match_phy_device() API.
However, it does not handle the C45 ID. If C45 was used to access
TJA11xx, match_phy_device() would always return false due to
phydev->phy_id only used by C22 being empty, resulting in the
generic phy driver being used for TJA11xx PHYs.
Therefore, check phydev->c45_ids.device_ids[MDIO_MMD_PMAPMD] when
using C45.
