The devlink_resources_unregister() used second parameter as an
entry point for the recursive removal of devlink resources. None
of the callers outside of devlink core needed to use this field,
so let's remove it.
As part of this removal, the "struct devlink_resource" was moved
from .h to .c file as it is not possible to use in any place in
the code except devlink.c.

In the blamed commit, the second memory resource was not considered
anymore as optional. On some platforms like sparx5 the second resource
is optional. So add it back as optional and restore the comment that
says so.

We have VLAN PTP support(via get_ts_info) on kernel, and bond support(by
getting active interface via netlink message) on userspace tool linuxptp.
But there are always some users who want to use PTP with VLAN over bond,
which is not able to do with the current implementation.
This patch passed get_ts_info and SIOC[SG]HWTSTAMP ioctl to active device
with bond mode active-backup/tlb/alb. With this users could get kernel native
bond or VLAN over bond PTP support.
Test with ptp4l and it works with VLAN over bond after this patch:

Fix a bug in which the receiving of packets can stop in the zero-copy
driver. Ice HW ignores 3 lower bits from QRX_TAIL register, which means
that tail is bumped only on intervals of 8. Currently with XSK RX
batching in place, ice_alloc_rx_bufs_zc() clears the status_error0 only
of the last descriptor that has been allocated/taken from the XSK buffer
pool. status_error0 includes DD bit that is looked upon by the
ice_clean_rx_irq_zc() to tell if a descriptor can be processed.
The bug can be triggered when driver updates the ntu but not the
QRX_TAIL, so HW wouldn't have a chance to write to the ready
descriptors. Later on driver moves the ntc to the mentioned set of
descriptors and interprets them as a ready to be processed, since
corresponding DD bits were not cleared nor any writeback has happened
that would clear it. This can then lead to ntc == ntu case which means
that ring is empty and no further packet processing.
Fix the XSK traffic hang that can be observed when l2fwd scenario from
xdpsock is used by making sure that status_error0 is cleared for each
descriptor that is fed to HW and therefore we are sure that driver will
not processed non-valid DD bits. This will also prevent the driver from
processing the descriptors that were allocated in favor of the
previously processed ones, but writeback didn't happen yet.

dwmac-qcom-ethqos currently exposes a mechanism to dump rgmii registers
after the 'stmmac_dvr_probe()' returns. However with commit
5ec55823438e ("net: stmmac: add clocks management for gmac driver"),
we now let 'pm_runtime_put()' disable the clocks before returning from
'stmmac_dvr_probe()'.
This causes a crash when 'rgmii_dump()' register dumps are enabled,
as the clocks are already off.
Since other dwmac drivers (possible future users as well) might
require a similar register dump feature, introduce a platform level
callback to allow the same.
This fixes the crash noticed while enabling rgmii_dump() dumps in
dwmac-qcom-ethqos driver as well. It also allows future changes
to keep a invoking the register dump callback from the correct
place inside 'stmmac_dvr_probe()'.

If we're being delivered packets from multiple CPUs so quickly that the
ring lock is contended for CPU tries, then it's safe to assume that the
queue is near capacity anyway, so just drop the packet rather than
spinning. This helps deal with multicore DoS that can interfere with
data path performance. It _still_ does not completely fix the issue, but
it again chips away at it.

Apparently the spinlock on incoming_handshake's skb_queue is highly
contended, and a torrent of handshake or cookie packets can bring the
data plane to its knees, simply by virtue of enqueueing the handshake
packets to be processed asynchronously. So, we try switching this to a
ring buffer to hopefully have less lock contention. This alleviates the
problem somewhat, though it still isn't perfect, so future patches will
have to improve this further. However, it at least doesn't completely
diminish the data plane.

Each peer's endpoint contains a dst_cache entry that takes a reference
to another netdev. When the containing namespace exits, we take down the
socket and prevent future sockets from being created (by setting
creating_net to NULL), which removes that potential reference on the
netns. However, it doesn't release references to the netns that a netdev
cached in dst_cache might be taking, so the netns still might fail to
exit. Since the socket is gimped anyway, we can simply clear all the
dst_caches (by way of clearing the endpoint src), which will release all
references.
However, the current dst_cache_reset function only releases those
references lazily. But it turns out that all of our usages of
wg_socket_clear_peer_endpoint_src are called from contexts that are not
exactly high-speed or bottle-necked. For example, when there's
connection difficulty, or when userspace is reconfiguring the interface.
And in particular for this patch, when the netns is exiting. So for
those cases, it makes more sense to call dst_release immediately. For
that, we add a small helper function to dst_cache.
This patch also adds a test to netns.sh from Hangbin Liu to ensure this
doesn't regress.

When link modes were initially added in commit 2c762679435dc

later updated for the new ethtool API in commit 3d8f7cc78d0eb
("net: mlx4: use new ETHTOOL_G/SSETTINGS API") the only 1/10G non-baseT
link modes configured were 1000baseKX, 10000baseKX4 and 10000baseKR.
It looks like these got picked to represent other modes since nothing
better was available.

Switch seville to use of_mdiobus_register(bus, NULL) instead of just
mdiobus_register. This code is about to be pulled into a separate module
that can optionally define ports by the device_node.

Utilize regmap instead of __iomem to perform indirect mdio access. This
will allow for custom regmaps to be used by way of the mscc_miim_setup
function.

This patch adds support for MAC table operations like add and forget.
Also add the functionality to read the MAC address from DT, if there is
no MAC set in DT it would use a random one.

IXP4xx is being migrated to device tree only. Convert this
driver to use device tree probing.
Pull in all the boardfile code from the one boardfile and
make it local, pull all the boardfile parameters from the
device tree instead of the board file.

A contact at Realtek has clarified what exactly the units of RGMII RX
delay are. The answer is that the unit of RX delay is "about 0.3 ns".
Take this into account when parsing rx-internal-delay-ps by
approximating the closest step value. Delays of more than 2.1 ns are
rejected.
This obviously contradicts the previous assumption in the driver that a
step value of 4 was "about 2 ns", but Realtek also points out that it is
easy to find more than one RX delay step value which makes RGMII work.
