d69778df1a net: amd: mvme147: Fix probe banner message
[ Upstream commit 82c5b53140faf89c31ea2b3a0985a2f291694169 ]

Currently this driver prints this line with what looks like
a rogue format specifier when the device is probed:
[    2.840000] eth%d: MVME147 at 0xfffe1800, irq 12, Hardware Address xx:xx:xx:xx:xx:xx

Change the printk() for netdev_info() and move it after the
registration has completed so it prints out the name of the
interface properly.

fd0a3436e4 r8169: avoid unsolicited interrupts
[ Upstream commit 10ce0db787004875f4dba068ea952207d1d8abeb ]

It was reported that after resume from suspend a PCI error is logged
and connectivity is broken. Error message is:
PCI error (cmd = 0x0407, status_errs = 0x0000)
The message seems to be a red herring as none of the error bits is set,
and the PCI command register value also is normal. Exception handling
for a PCI error includes a chip reset what apparently brakes connectivity
here. The interrupt status bit triggering the PCI error handling isn't
actually used on PCIe chip versions, so it's not clear why this bit is
set by the chip. Fix this by ignoring this bit on PCIe chip versions.

f93e3153c5 net: macb: Avoid 20s boot delay by skipping MDIO bus registration for fixed-link PHY
commit d0c3601f2c4e12e7689b0f46ebc17525250ea8c3 upstream.

A boot delay was introduced by commit 79540d133ed6 ("net: macb: Fix
handling of fixed-link node"). This delay was caused by the call to
`mdiobus_register()` in cases where a fixed-link PHY was present. The
MDIO bus registration triggered unnecessary PHY address scans, leading
to a 20-second delay due to attempts to detect Clause 45 (C45)
compatible PHYs, despite no MDIO bus being attached.

The commit 79540d133ed6 ("net: macb: Fix handling of fixed-link node")
was originally introduced to fix a regression caused by commit
7897b071ac3b4 ("net: macb: convert to phylink"), which caused the driver
to misinterpret fixed-link nodes as PHY nodes. This resulted in warnings
like:
mdio_bus f0028000.ethernet-ffffffff: fixed-link has invalid PHY address
mdio_bus f0028000.ethernet-ffffffff: scan phy fixed-link at address 0
...
mdio_bus f0028000.ethernet-ffffffff: scan phy fixed-link at address 31

This patch reworks the logic to avoid registering and allocation of the
MDIO bus when:
  - The device tree contains a fixed-link node.
  - There is no "mdio" child node in the device tree.

If a child node named "mdio" exists, the MDIO bus will be registered to
support PHYs  attached to the MACB's MDIO bus. Otherwise, with only a
fixed-link, the MDIO bus is skipped.

Tested on a sama5d35 based system with a ksz8863 switch attached to
macb0.

e28819c79a igb: Do not bring the device up after non-fatal error
[ Upstream commit 330a699ecbfc9c26ec92c6310686da1230b4e7eb ]

Commit 004d25060c78 ("igb: Fix igb_down hung on surprise removal")
changed igb_io_error_detected() to ignore non-fatal pcie errors in order
to avoid hung task that can happen when igb_down() is called multiple
times. This caused an issue when processing transient non-fatal errors.
igb_io_resume(), which is called after igb_io_error_detected(), assumes
that device is brought down by igb_io_error_detected() if the interface
is up. This resulted in panic with stacktrace below.

To fix this issue igb_io_resume() checks if the interface is running and
the device is not down this means igb_io_error_detected() did not bring
the device down and there is no need to bring it up.

6bb154f4ac ice: fix VLAN replay after reset
[ Upstream commit 0eae2c136cb624e4050092feb59f18159b4f2512 ]

There is a bug currently when there are more than one VLAN defined
and any reset that affects the PF is initiated, after the reset rebuild
no traffic will pass on any VLAN but the last one created.

This is caused by the iteration though the VLANs during replay each
clearing the vsi_map bitmap of the VSI that is being replayed.  The
problem is that during rhe replay, the pointer to the vsi_map bitmap
is used by each successive vlan to determine if it should be replayed
on this VSI.

The logic was that the replay of the VLAN would replace the bit in the map
before the next VLAN would iterate through.  But, since the replay copies
the old bitmap pointer to filt_replay_rules and creates a new one for the
recreated VLANS, it does not do this, and leaves the old bitmap broken
to be used to replay the remaining VLANs.

Since the old bitmap will be cleaned up in post replay cleanup, there is
no need to alter it and break following VLAN replay, so don't clear the
bit.

slotted in software checksumming in the driver if hardware could not
do it.

This will however upset TSO (TCP Segment Offloading). Typical
error dumps includes this:

skb len=2961 headroom=222 headlen=66 tailroom=0
(...)
WARNING: CPU: 0 PID: 956 at net/core/dev.c:3259 skb_warn_bad_offload+0x7c/0x108
gemini-ethernet-port: caps=(0x0000010000154813, 0x00002007ffdd7889)

And the packets do not go through.

The TSO implementation is bogus: a TSO enabled driver must propagate
the skb_shinfo(skb)->gso_size value to the TSO engine on the NIC.

Drop the size check and TSO offloading features for now: this
needs to be fixed up properly.

After this ethernet works fine on Gemini devices with a direct connected
PHY such as D-Link DNS-313.

Also tested to still be working with a DSA switch using the Gemini
ethernet as conduit interface.

b57e5dc84b r8169: add tally counter fields added with RTL8125
[ Upstream commit ced8e8b8f40accfcce4a2bbd8b150aa76d5eff9a ]

RTL8125 added fields to the tally counter, what may result in the chip
dma'ing these new fields to unallocated memory. Therefore make sure
that the allocated memory area is big enough to hold all of the
tally counter values, even if we use only parts of it.

9f91978b91 net: stmmac: Fix zero-division error when disabling tc cbs
commit 675faf5a14c14a2be0b870db30a70764df81e2df upstream.

The commit b8c43360f6e4 ("net: stmmac: No need to calculate speed divider
when offload is disabled") allows the "port_transmit_rate_kbps" to be
set to a value of 0, which is then passed to the "div_s64" function when
tc-cbs is disabled. This leads to a zero-division error.

When tc-cbs is disabled, the idleslope, sendslope, and credit values the
credit values are not required to be configured. Therefore, adding a return
statement after setting the txQ mode to DCB when tc-cbs is disabled would
prevent a zero-division error.

f7cf43b465 net: atlantic: Avoid warning about potential string truncation
[ Upstream commit 5874e0c9f25661c2faefe4809907166defae3d7f ]

W=1 builds with GCC 14.2.0 warn that:

.../aq_ethtool.c:278:59: warning: ‘%d’ directive output may be truncated writing between 1 and 11 bytes into a region of size 6 [-Wformat-truncation=]

      |                                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

tc is always in the range 0 - cfg->tcs. And as cfg->tcs is a u8,
the range is 0 - 255. Further, on inspecting the code, it seems
that cfg->tcs will never be more than AQ_CFG_TCS_MAX (8), so
the range is actually 0 - 8.

So, it seems that the condition that GCC flags will not occur.
But, nonetheless, it would be nice if it didn't emit the warning.

It seems that this can be achieved by changing the format specifier
from %d to %u, in which case I believe GCC recognises an upper bound
on the range of tc of 0 - 255. After some experimentation I think
this is due to the combination of the use of %u and the type of
cfg->tcs (u8).

Empirically, updating the type of the tc variable to unsigned int
has the same effect.

As both of these changes seem to make sense in relation to what the code
is actually doing - iterating over unsigned values - do both.

Compile tested only.

Increase size of queue_name buffer from 30 to 31 to accommodate
the largest string written to it. This avoids truncation in
the possibly unlikely case where the string is name is the
maximum size.
