soft reset
This driver has two separate reset sequence in different places:
- gpio/HW reset on start of ksz_switch_register()
- SW reset on start of ksz_setup()
The second one will overwrite drive strength configuration made in the
ksz_switch_register().
To fix it, move ksz_parse_drive_strength() from ksz_switch_register() to
ksz_setup().

When auxiliary_device_add() returns error and then calls
auxiliary_device_uninit(), Callback function pdsc_auxbus_dev_release
calls kfree(padev) to free memory. We shouldn't call kfree(padev)
again in the error handling path.
Fix this by cleaning up the redundant kfree() and putting
the error handling back to where the errors happened.

This bug was noticed while re-implementing parts of the kernel
driver in userspace using spidev. The goal was to enable some
of the errata workarounds that Microchip describes in their
errata sheet [1].
Both the errata sheet and the regular datasheet of e.g. the KSZ8795
imply that you need to do this for indirect register accesses:
- write a 16-bit value to a control register pair (this value
consists of the indirect register table, and the offset inside
the table)
- either read or write an 8-bit value from the data storage
register (indicated by REG_IND_BYTE in the kernel)
The current implementation has the order swapped. It can be
proven, by reading back some indirect register with known content
(the EEE register modified in ksz8_handle_global_errata() is one of
these), that this implementation does not work.
Private discussion with Oleksij Rempel of Pengutronix has revealed
that the workaround was apparantly never tested on actual hardware.

Older versions of GCC really want to know the full definition
of the type involved in rcu_assign_pointer().
struct dpll_pin is defined in a local header, net/core can't
reach it. Move all the netdev <> dpll code into dpll, where
the type is known. Otherwise we'd need multiple function calls
to jump between the compilation units.
This is the same problem the commit under fixes was trying to address,
but with rcu_assign_pointer() not rcu_dereference().
Some of the exports are not needed, networking core can't
be a module, we only need exports for the helpers used by
drivers.

Commit 9b0ed890ac2a ("bonding: do not report NETDEV_XDP_ACT_XSK_ZEROCOPY")
changed the driver from reporting everything as supported before a device
was bonded into having the driver report that no XDP feature is supported
until a real device is bonded as it seems to be more truthful given
eventually real underlying devices decide what XDP features are supported.
The change however did not take into account when all slave devices get
removed from the bond device. In this case after 9b0ed890ac2a, the driver
keeps reporting a feature mask of 0x77, that is, NETDEV_XDP_ACT_MASK &
~NETDEV_XDP_ACT_XSK_ZEROCOPY whereas it should have reported a feature
mask of 0.
Fix it by resetting XDP feature flags in the same way as if no XDP program
is attached to the bond device. This was uncovered by the XDP bond selftest
which let BPF CI fail. After adjusting the starting masks on the latter
to 0 instead of NETDEV_XDP_ACT_MASK the test passes again together with
this fix.

When a frame can not be transmitted in XDP_REDIRECT
(e.g. due to a full queue), it is necessary to free
it by calling xdp_return_frame_rx_napi.
However, this is the responsibility of the caller of
the ndo_xdp_xmit (see for example bq_xmit_all in
kernel/bpf/devmap.c) and thus calling it inside
igc_xdp_xmit (which is the ndo_xdp_xmit of the igc
driver) as well will lead to memory corruption.
In fact, bq_xmit_all expects that it can return all
frames after the last successfully transmitted one.
Therefore, break for the first not transmitted frame,
but do not call xdp_return_frame_rx_napi in igc_xdp_xmit.
This is equally implemented in other Intel drivers
such as the igb.
There are two alternatives to this that were rejected:
1. Return num_frames as all the frames would have been
transmitted and release them inside igc_xdp_xmit.
While it might work technically, it is not what
the return value is meant to represent (i.e. the
number of SUCCESSFULLY transmitted packets).
2. Rework kernel/bpf/devmap.c and all drivers to
support non-consecutively dropped packets.
Besides being complex, it likely has a negative
performance impact without a significant gain
since it is anyway unlikely that the next frame
can be transmitted if the previous one was dropped.
The memory corruption can be reproduced with
the following script which leads to a kernel panic
after a few seconds. It basically generates more
traffic than a i225 NIC can transmit and pushes it
via XDP_REDIRECT from a virtual interface to the
physical interface where frames get dropped.

The E800 series hardware uses the same iAVF driver as older devices,
including the virtchnl negotiation scheme.
This negotiation scheme includes a mechanism to determine what type of RSS
should be supported, including RSS over PF virtchnl messages, RSS over
firmware AdminQ messages, and RSS via direct register access.
The PF driver will always prefer VIRTCHNL_VF_OFFLOAD_RSS_PF if its
supported by the VF driver. However, if an older VF driver is loaded, it
may request only VIRTCHNL_VF_OFFLOAD_RSS_REG or VIRTCHNL_VF_OFFLOAD_RSS_AQ.
The ice driver happily agrees to support these methods. Unfortunately, the
underlying hardware does not support these mechanisms. The E800 series VFs
don't have the appropriate registers for RSS_REG. The mailbox queue used by
VFs for VF to PF communication blocks messages which do not have the
VF-to-PF opcode.
Stop lying to the VF that it could support RSS over AdminQ or registers, as
these interfaces do not work when the hardware is operating on an E800
series device.
In practice this is unlikely to be hit by any normal user. The iAVF driver
has supported RSS over PF virtchnl commands since 2016, and always defaults
to using RSS_PF if possible.
In principle, nothing actually stops the existing VF from attempting to
access the registers or send an AQ command. However a properly coded VF
will check the capability flags and will report a more useful error if it
detects a case where the driver does not support the RSS offloads that it
does.

Fix softirq's not being handled during napi_schedule() call when

The issue can be seen on ifdown:

On Goldmont p2sb_bar() only ever gets called for 2 devices, the actual P2SB
devfn 13,0 and the SPI controller which is part of the P2SB, devfn 13,2.
But the current p2sb code tries to cache BAR0 info for all of
devfn 13,0 to 13,7 . This involves calling pci_scan_single_device()
for device 13 functions 0-7 and the hw does not seem to like
pci_scan_single_device() getting called for some of the other hidden
devices. E.g. on an ASUS VivoBook D540NV-GQ065T this leads to continuous
ACPI errors leading to high CPU usage.
Fix this by only caching BAR0 info and thus only calling
pci_scan_single_device() for the P2SB and the SPI controller.

Based on the static analyzis of the code it looks like when an entry
from the MAC table was removed, the entry was still used after being
freed. More precise the vid of the mac_entry was used after calling
devm_kfree on the mac_entry.
The fix consists in first using the vid of the mac_entry to delete the
entry from the HW and after that to free it.

syzbot triggered a bug in geneve_rx() [1]
Issue is similar to the one I fixed in commit 8d975c15c0cd
("ip6_tunnel: make sure to pull inner header in __ip6_tnl_rcv()")
We have to save skb->network_header in a temporary variable
in order to be able to recompute the network_header pointer
after a pskb_inet_may_pull() call.
pskb_inet_may_pull() makes sure the needed headers are in skb->head.

Pull firewire fixes from Takashi Sakamoto:
"A workaround to suppress the continuous bus resets in the case that
older devices are connected to the modern 1394 OHCI hardware and
devices
In IEEE 1394 Amendment (IEEE 1394a-2000), the short bus reset is added
to resolve the shortcomings of the long bus reset in IEEE 1394-1995.
However, it is well-known that the solution is not necessarily
effective in the mixing environment that both IEEE 1394-1995 PHY and
IEEE 1394a-2000 (or later) PHY exist, as described in section 8.4.6.2
of IEEE 1394a-2000.
The current implementation of firewire stack schedules the short bus
reset when attempting to resolve the mismatch of gap count in the
certain generation of bus topology. It can cause the continuous bus
reset in the issued environment.
The workaround simply uses the long bus reset instead of the short bus
reset. It is desirable to detect whether the issued environment or
not. However, the way to access PHY registers from remote note is
firstly defined in IEEE 1394a-2000, thus it is not available in the
case"

timestamping NAPI poll context
The NAPI poll context is a softirq context. Do not use normal spinlock API
in this context to prevent concurrency issues.

occurs after populating the metadata_map
Just simply reordering the functions mlx5e_ptp_metadata_map_put and
mlx5e_ptpsq_track_metadata in the mlx5e_txwqe_complete context is not good
enough since both the compiler and CPU are free to reorder these two
functions. If reordering does occur, the issue that was supposedly fixed by
7e3f3ba97e6c ("net/mlx5e: Track xmit submission to PTP WQ after populating
metadata map") will be seen. This will lead to NULL pointer dereferences in
mlx5e_ptpsq_mark_ts_cqes_undelivered in the NAPI polling context due to the
tracking list being populated before the metadata map.

The packet number attribute of the SA is incremented by the device rather
than the software stack when enabling hardware offload. Because the packet
number attribute is managed by the hardware, the software has no insight
into the value of the packet number attribute actually written by the
device.
Previously when MACsec offload was enabled, the hardware object for
handling the offload was destroyed when the SA was disabled. Re-enabling
the SA would lead to a new hardware object being instantiated. This new
hardware object would not have any recollection of the correct packet
number for the SA. Instead, destroy the flow steering rule when
deactivating the SA and recreate it upon reactivation, preserving the
original hardware object.

Downgrade the print from mlx5_core_warn() to mlx5_core_dbg(), as it
is just a statement of fact that firmware doesn't support ignore flow
level.
And change the wording to "firmware flow level support is missing", to
make it more accurate.

Functions which can't access MFRL (Management Firmware Reset Level)
register, have no use of fw_reset structures or events. Remove fw_reset
structures allocation and registration for fw reset events notifications
for these functions.
Having the devlink param enable_remote_dev_reset on functions that don't
have this capability is misleading as these functions are not allowed to
influence the reset flow. Hence, this patch removes this parameter for
such functions.
In addition, return not supported on devlink reload action fw_activate
for these functions.

The checking in the cited commit is not accurate. In the common case,
VF destination is internal, and uplink destination is external.
However, uplink destination with packet reformat is considered as
internal because firmware uses LB+hairpin to support it. Update the
checking so header rewrite rules with both internal and external
destinations are not allowed.
