The recent firmware interface change has added 2 counters in struct
rx_port_stats_ext. This caused 2 stray ethtool counters to be
displayed.
Since new counters are added from time to time, fix it so that the
ethtool logic will only display up to the maximum known counters.
These 2 counters are not used by production firmware yet.

In iavf_down, we're skipping the scheduling of certain operations if
the driver is being removed. However, the IAVF_FLAG_AQ_DISABLE_QUEUES
request must not be skipped in this case, because iavf_close waits
for the transition to the __IAVF_DOWN state, which happens in
iavf_virtchnl_completion after the queues are released.
Without this fix, "rmmod iavf" takes half a second per interface that's
up and prints the "Device resources not yet released" warning.

This board was an early prototype platform for early SH4 CPUs and related
to the already removed SH5 cayman platform.
The microdev board itself has been kept in the tree for this long despite
being in a bad shape even 20 years ago when it got merged, with no working
PCI support and ugly workarounds for its I/O port implementation that
try to emulate PC style peripheral access despite being quite different
in reality.
As far as I can tell, the ethernet, display, USB and PCI devices on it
already broke at some point (afbb9d8d5266b, 46bc85872040a), so I think
we can just removeit entirely.

Currently there is a device tree entry called "local-mac-address"
which can be filled by the bootloader or manually set.This is
useful when the user does not want to use the MAC address
programmed into the SoC.
Currently, the davinci_emac reads the MAC from the DT, copies
it from pdata->mac_addr to priv->mac_addr, then blindly overwrites
it by reading from registers in the SoC, and falls back to a
random MAC if it's still not valid. This completely ignores any
MAC address in the device tree.
In order to use the local-mac-address, check to see if the contents
of priv->mac_addr are valid before falling back to reading from the
SoC when the MAC address is not valid.

Currently all RX frames are timestamped which results in a performance
penalty when timestamping is not needed. The default is now being
changed to not timestamp any Rx frames (HWTSTAMP_FILTER_NONE), but
support has been added to allow changing the desired RX timestamping
mode (HWTSTAMP_FILTER_ALL - which was the previous setting and
HWTSTAMP_FILTER_PTP_V2_EVENT are now supported) using
SIOCSHWTSTAMP. All settings were tested using the hwstamp_ctl application.
It is also noted that ptp4l, when started, preconfigures the device to
timestamp using HWTSTAMP_FILTER_PTP_V2_EVENT, so this driver continues
to work properly "out of the box".

Coldfire platforms with data caches can't properly implement
dma_alloc_coherent and currently just return noncoherent memory from
dma_alloc_coherent.
The fec driver than works around this with a flush of all caches in the
receive path. Make this hack a little less bad by using the explicit
dma_alloc_noncoherent API and documenting the hacky cache flushes so
that the DMA API level hack can be removed.
Also replace the check for CONFIG_M532x for said hack with a check
for COLDFIRE && !COLDFIRE_COHERENT_DMA. While m532x is the only such
platform with a fec module, this makes the code more consistent and
easier to follow.

Upon boot up, the driver will configure the MAC capabilities based on
the maximum number of tx and rx queues. When the user changes the
tx queues to single queue, the MAC should be capable of supporting Half
Duplex, but the driver does not update the MAC capabilities when it is
configured so.
Using the stmmac_reinit_queues() to check the number of tx queues
and set the MAC capabilities accordingly.

Commit b0377116decd ("net: ethernet: Use device_get_match_data()") dropped
the unconditional use of xgene_enet_of_match resulting in this warning:
drivers/net/ethernet/apm/xgene/xgene_enet_main.c:2004:34: warning: unused variable 'xgene_enet_of_match' [-Wunused-const-variable]
The fix is to drop of_match_ptr() which is not necessary because DT is
always used for this driver (well, it could in theory support ACPI only,
but CONFIG_OF is always enabled for arm64).

When a programming status desc is encountered on the rx_ring,
next_to_process is bumped along with cleaned_count but next_to_clean is
not. This causes I40E_DESC_UNUSED() macro to misbehave resulting in
overwriting whole ring with new buffers.
Update next_to_clean to point to next_to_process on seeing a programming
status desc if not in the middle of handling a multi-frag packet. Also,
bump cleaned_count only for such case as otherwise next_to_clean buffer
may be returned to hardware on reaching clean_threshold.

The 'ethtool_convert_link_mode_to_legacy_u32' method does not allow us to

'ethtool_link_ksettings_test_link_mode' to advertise supported speed and

The list iterator in a list_for_each_entry() loop can never be NULL.
If the loop exits without hitting a break then the iterator points
to an offset off the list head and dereferencing it is an out of
bounds access.
Before we transitioned to using list_for_each_entry() loops, then
it was possible for "entry" to be NULL and the comments mention
this. I have updated the comments to match the new code.

When we exit a list_for_each_entry() without hitting a break statement,
the list iterator isn't NULL, it just point to an offset off the
list_head. In that situation, it wouldn't be too surprising for
entry->free to be true and we end up corrupting memory.
The way to test for these is to just set a flag.

The ice_find_netlist_node function was introduced in commit 8a3a565ff210
("ice: add admin commands to access cgu configuration"). Variations of this
function were reviewed concurrently on both intel-wired-lan[1][2], and
netdev [3][4]
[1]: https://lore.kernel.org/intel-wired-lan/20230913204943.1051233-7-vadim.fedorenko@linux.dev/

[4]: https://lore.kernel.org/netdev/20230913204943.1051233-7-vadim.fedorenko@linux.dev/
The variant I posted had a few changes due to review feedback which were
never incorporated into the DPLL series:
* Replace the references to ancient and long removed ICE_SUCCESS and
ICE_ERR_DOES_NOT_EXIST status codes in the function comment.
* Return -ENOENT instead of -ENOTBLK, as a more common way to indicate that
an entry doesn't exist.
* Avoid the use of memset() and use simple static initialization for the
cmd variable.
* Use FIELD_PREP to assign the node_type_ctx.
* Remove an unnecessary local variable to keep track of rec_node_handle,
just pass the node_handle pointer directly into ice_aq_get_netlist_node.

Implement ops needed to set MSI-X vector count on VF.
sriov_get_vf_total_msix() should return total number of MSI-X that can
be used by the VFs. Return the value set by devlink resources API
(pf->req_msix.vf).
sriov_set_msix_vec_count() will set number of MSI-X on particular VF.
Disable VF register mapping, rebuild VSI with new MSI-X and queues
values and enable new VF register mapping.
For best performance set number of queues equal to number of MSI-X.

Store the amount of MSI-X per VF instead of storing it in pf struct. It
is used to calculate number of q_vectors (and queues) for VF VSI.
This is necessary because with follow up changes the number of MSI-X can
be different between VFs. Use it instead of using pf->vf_msix value in
all cases.
