A flexible action instance allows, given a set of ops, creating, committing
and sharing a set of ACL action blocks. The flexible action instance in
question is using the spectrum KVD linear space to store the flexible
action sets.
Move this flexible action instance to the common spectrum struct to allow
other users (such as multicast router) to get that functionality.

The multicast router offloading code is going to require the counter_pools
initialization to occur before the router initialization, thus, change the
spectrum initialization order to fix it.

Since the integration of PHYLINK, the configuration option which
used to be under the PHY infrastructure menu in menuconfig ended
up one level up (the network device driver section)
By placing PHYLINK option right after PHYLIB entry, it broke the
way Kconfig used to build the menu. See kconfig-language.txt, section
"Menu structure", 2nd method.
This is fixed by placing the PHYLINK option just before PHYLIB.

There are several problems with commit 10377ba7673d ("net: systemport:
Support 64bit statistics", first one got fixed in 7095c973453e ("net:
systemport: Fix 64-bit stats deadlock").
The second problem is that this specific code updates the
stats64.tx_{packets,bytes} from ndo_get_stats64() and that is what we
are returning to ethtool -S. If we are not running a tool that involves
calling ndo_get_stats64(), then we won't get updated ethtool stats.
The solution to this is to update the stats from both call sites,
factoring that into a specific function, While at it, don't just check
the sizeof() but also the type of the statistics in order to use the
64-bit stats seqlock.

It seems we have to be more careful in napi_complete_done()

When such interrupts occur there is not much we can do.
Dropping the whole ring doesn't help and only produces high packet loss.
If we just ignore the interrupt the mac will drop one or few packets instead of the whole ring.

The driver doesn't support events from address families other than IPv4
and IPv6, so ignore them. Otherwise, we risk queueing a work item before
it's initialized.
This can happen in case a VRF is configured when MROUTE_MULTIPLE_TABLES
is enabled, as the VRF driver will try to add an l3mdev rule for the
IPMR family.

If the network interface is kept running during suspend, the net core
may call net_device_ops.ndo_start_xmit() while the Ethernet device is
still suspended, which may lead to a system crash.
E.g. on sh73a0/kzm9g and r8a73a4/ape6evm, the external Ethernet chip is
driven by a PM controlled clock. If the Ethernet registers are accessed
while the clock is not running, the system will crash with an imprecise
external abort.
As this is a race condition with a small time window, it is not so easy
to trigger at will. Using pm_test may increase your chances:
# echo 0 > /sys/module/printk/parameters/console_suspend
# echo platform > /sys/power/pm_test
# echo mem > /sys/power/state
To fix this, make sure the network interface is quietened during
suspend.

We can enter a deadlock situation because there is no sufficient protection
when ndo_get_stats64() runs in process context to guard against RX or TX NAPI
contexts running in softirq, this can lead to the following lockdep splat and
actual deadlock was experienced as well with an iperf session in the background
and a while loop doing ifconfig + ethtool.

I have no idea what this warning is even trying to say, but it does
seem like a false positive. Reordering the initialization in to match
the structure definition gets rid of the warning, and might also avoid
whatever gcc thinks is wrong here.

on very fast-booting machines it may not be ready for operation
when driver probes the device. There is also a version of the
flash in the wild where NSP tries to train the links as part
of init. To wait for NSP initialization we should make sure
its resource has already been added to the resource table.
NSP adds itself there as last step of init.

Commit 8b426dc54cf4 ("bonding: remove hardcoded value") changed the
default value for tlb_dynamic_lb which lead to either broken ALB mode
(since tlb_dynamic_lb can be changed only in TLB) or setting TLB mode
with tlb_dynamic_lb equal to 0.
The first issue was recently fixed by setting tlb_dynamic_lb to 1 always
when switching to ALB mode, but the default value is still wrong and
we'll enter TLB mode with tlb_dynamic_lb equal to 0 if the mode is
changed via netlink or sysfs. In order to restore the previous behaviour
and default value simply remove the mode check around the default param
initialization for tlb_dynamic_lb which will always set it to 1 as
before.

When removing the offloading of mirred actions under
matchall classifiers, mlxsw would find the destination port
associated with the offloaded action and utilize it for undoing
the configuration.
Depending on the order by which ports are removed, it's possible that
the destination port would get removed before the source port.
In such a scenario, when actions would be flushed for the source port
mlxsw would perform an illegal dereference as the destination port is
no longer listed.
Since the only item necessary for undoing the configuration on the
destination side is the port-id and that in turn is already maintained
by mlxsw on the source-port, simply stop trying to access the
destination port and use the port-id directly instead.

Commit cbf5ecb30560 ("net: bonding: Fix transmit load balancing in
balance-alb mode") tried to fix transmit dynamic load balancing in
balance-alb mode, which wasn't working after commit 8b426dc54cf4
("bonding: remove hardcoded value").
It turned out that my previous patch only fixed the case when
balance-alb was specified as bonding module parameter, and not when
balance-alb mode was set using /sys/class/net/*/bonding/mode (the most
common usage). In the latter case, tlb_dynamic_lb was set up according
to the default mode of the bonding interface, which happens to be
balance-rr.
This additional patch addresses this issue by setting up tlb_dynamic_lb
to 1 if "mode" is set to balance-alb through the sysfs interface.
I didn't add code to change tlb_balance_lb back to the default value for
other modes, because "mode" is usually set up only once during
initialization, and it's not worthwhile to change the static variable
bonding_defaults in bond_main.c to a global variable just for this
purpose.
Commit 8b426dc54cf4 also changes the value of tlb_dynamic_lb for
balance-tlb mode if it is set up using the sysfs interface. I didn't
change that behavior, because the value of tlb_balance_lb can be changed
using the sysfs interface for balance-tlb, and I didn't like changing
the default value back and forth for balance-tlb.
As for balance-alb, /sys/class/net/*/bonding/tlb_balance_lb cannot be
written to. However, I think balance-alb with tlb_dynamic_lb set to 0
is not an intended usage, so there is little use making it writable at
this moment.

When a virtual device is added dynamically (via host console), then
the vmbus sends an offer message for the primary channel. The processing
of this message for networking causes the network device to then
initialize the sub channels.
The problem is that setting up the sub channels needs to wait until
the subsequent subchannel offers have been processed. These offers
come in on the same ring buffer and work queue as where the primary
offer is being processed; leading to a deadlock.
This did not happen in older kernels, because the sub channel waiting
logic was broken (it wasn't really waiting).
The solution is to do the sub channel setup in its own work queue
context that is scheduled by the primary channel setup; and then
happens later.

The current code does not handle correctly the access to the upper page
in case of SFP/SFP+ EEPROM. In that case the offset should be local
and the I2C address should be changed.

There is a typo here so we accidentally free "skb" instead of "skbn".
It leads to a double free and a leak. After discussing with Subash,
it's better to just move the check before the allocation and avoid the
need to free.

This reverts commit 95b80bf3db03c2bf572a357cf74b9a6aefef0a4a ("mdio_bus:
Remove unneeded gpiod NULL check"), this commit assumed that GPIOLIB
checks for NULL descriptors, so it's safe to drop them, but it is not
when CONFIG_GPIOLIB is disabled in the kernel. If we do call
gpiod_set_value_cansleep() on a GPIO descriptor we will issue warnings
coming from the inline stubs declared in include/linux/gpio/consumer.h.
