Modify set actions are not supported on both tx
and rx, added a check for that.
Also refactored the code in a way that every modify
action has his own functions, this needed so in the
future we could add copy action more smoothly.

In the flowtables offload all the devices in the flowtables
share the same flow_block. An offload rule will be installed on
all the devices. This scenario is not correct.
It is no problem if there are only two devices in the flowtable,
The rule with ingress and egress on the same device can be reject
by driver.
But more than two devices in the flowtable will install the wrong
rules on hardware.
For example:
Three devices in a offload flowtables: dev_a, dev_b, dev_c
A rule ingress from dev_a and egress to dev_b:
The rule will install on device dev_a.
The rule will try to install on dev_b but failed for ingress
and egress on the same device.
The rule will install on dev_c. This is not correct.
The flowtables offload avoid this case through restricting the ingress dev
with FLOW_DISSECTOR_KEY_META.
So the mlx5e driver also should support the FLOW_DISSECTOR_KEY_META parse.

since mlx5 hardware can segment correctly TSO packets on VXLAN over VLAN
topologies, CPU usage can improve significantly if we enable tunnel
offloads in dev->vlan_features, like it was done in the past with other

LOONGSON_CHIPCFG from a single-argument functional macro to a
non-functional macro with an mmio address in loongson2ef, but
loongson2_cpufreq still uses the notation of a functional macro call
expecting it to be an lvalue. Fixed based on loongson_suspend_enter.

The __setup_broadcast_timer() static function is only called in one

of __setup_broadcast_timer() and drop the latter.

When switching to using generic LED name composition mechanism via
devm_led_classdev_register_ext() API the part of code initializing
struct gpio_led's template name property was removed alongside.
It was however overlooked that the property was also passed to
devm_fwnode_get_gpiod_from_child() in place of "label" parameter,
which when set to NULL, results in gpio label being initialized to '?'.
It could be observed in debugfs and failed to properly identify
gpio association with LED consumer.
Fix this shortcoming by updating the GPIO label after the LED is
registered and its final name is known.

Commit 323ebb61e32b ("net: use listified RX for handling GRO_NORMAL
skbs") introduces batching of GRO_NORMAL packets in napi_frags_finish,
and commit 6570bc79c0df ("net: core: use listified Rx for GRO_NORMAL in
napi_gro_receive()") adds the same to napi_skb_finish. However,
dev_gro_receive (that is called just before napi_{frags,skb}_finish) can
also pass skbs to the networking stack: e.g., when the GRO session is
flushed, napi_gro_complete is called, which passes pp directly to
netif_receive_skb_internal, skipping napi->rx_list. It means that the
packet stored in pp will be handled by the stack earlier than the
packets that arrived before, but are still waiting in napi->rx_list. It
leads to TCP reorderings that can be observed in the TCPOFOQueue counter
in netstat.
This commit fixes the reordering issue by making napi_gro_complete also
use napi->rx_list, so that all packets going through GRO will keep their
order. In order to keep napi_gro_flush working properly, gro_normal_list
calls are moved after the flush to clear napi->rx_list.
iwlwifi calls napi_gro_flush directly and does the same thing that is
done by gro_normal_list, so the same change is applied there:
napi_gro_flush is moved to be before the flush of napi->rx_list.
A few other drivers also use napi_gro_flush (brocade/bna/bnad.c,
cortina/gemini.c, hisilicon/hns3/hns3_enet.c). The first two also use
napi_complete_done afterwards, which performs the gro_normal_list flush,
so they are fine. The latter calls napi_gro_receive right after
napi_gro_flush, so it can end up with non-empty napi->rx_list anyway.

write_wakeup can happen in parallel with close/hangup where tty->disc_data
is set to NULL and the netdevice is freed thus also freeing
disc_data. write_wakeup accesses disc_data so we must prevent close from
freeing the netdev while write_wakeup has a non-NULL view of
tty->disc_data.
We also need to make sure that accesses to disc_data are atomic. Which can
all be done with RCU.
This problem was found by Syzkaller on SLCAN, but the same issue is
reproducible with the SLIP line discipline using an LTP test based on the
Syzkaller reproducer.
A fix which didn't use RCU was posted by Hillf Danton.

The purpose of this was to keep all the queues updated with
the Rx sequence numbers because unlikely yet possible
situations where queues can't understand if a specific
packet needs to be dropped or not.
Unfortunately, it was reported that this caused issues in
our DMA engine. We don't fully understand how this is related,
but this is being currently debugged. For now, just don't send
this notification to the Rx queues. This de-facto reverts my
