For multiple scheduled scan support the driver needs to know which
scheduled scan request is being stopped. Pass the request id in the
.sched_scan_stop() callback.

This patch implements the idea to have multiple scheduled scan requests
running concurrently. It mainly illustrates how to deal with the incoming
request from user-space in terms of backward compatibility. In order to
use multiple scheduled scans user-space needs to provide a flag attribute
NL80211_ATTR_SCHED_SCAN_MULTI to indicate support. If not the request is
treated as a legacy scan.
Drivers currently supporting scheduled scan are now indicating they support
a single scheduled scan request. This obsoletes WIPHY_FLAG_SUPPORTS_SCHED_SCAN.

This patch adds hardware channel APIs support between
VF and PF for tunnelling configuration for the VFs.
According to that configuration VFs can run VXLAN/GENEVE/GRE
tunnels over it with tunnel features offloaded.
Using these APIs VF can also request for UDP ports configuration
to the PF, although PF and it's child VFs share the same port.

commit 4fbae7d83c98c30efc ("ipvlan: Introduce l3s mode") added
registration of netfilter hooks via nf_register_hooks().
This API provides the illusion of 'global' netfilter hooks by placing the
hooks in all current and future network namespaces.
In case of ipvlan the hook appears to be only needed in the namespace
that contains the ipvlan master device (i.e., usually init_net), so
placing them in all namespaces is not needed.
This switches ipvlan driver to pernet operations, and then only registers
hooks in namespaces where a ipvlan master device is set to l3s mode.
Extra care has to be taken when the master device is moved to another
namespace, as we might have to 'move' the netfilter hooks too.
This is done by storing the namespace the ipvlan port was created in.
On REGISTER event, do (un)register operations in the old/new namespaces.
This will also allow removal of the nf_register_hooks() in a future patch.

* Added defines for TX Event FIFO Element
* Adapted ndo_start_xmit function.
For versions >= v3.1.x it uses the TX FIFO to optimize the data
throughput. It stores the echo skb at the same index as in the
M_CAN's TX FIFO. The frame's message marker is set to this index.
This message marker is received in the TX Event FIFO after
the message was successfully transmitted. It is used to echo the
correct echo skb back to the network stack.
* Added m_can_echo_tx_event function. It reads all received
message markers in the TX Event FIFO and loops back the
corresponding echo skbs.
* ISR checks for new TX Event Entry interrupt for version >= 3.1.x.

This patch adapts the initialization of the M_CAN. So it can be used
with all versions >= 3.0.x.
Changes:
* Added version element to m_can_priv structure to hold M_CAN version.
* Renamed bittiming structs for version 3.0.x
* Added new bittiming structs for version >= 3.1.x
* Function alloc_m_can_dev takes 2 new arguments. The TX FIFO size and the
base address of the module.
* Chip configuration for CAN_CTRLMODE_LOOPBACK is changed: Enabled
CCCR_MON bit. In combination with TEST_LBCK it activates the internal
loopback mode. Leaving CCCR_MON '0' results in external loopback mode.
* Clocks are temporarily enabled by platform_propbe function in order to
allow read access to the Core Release register and the Control Register.
Registers are used to detect M_CAN version and optional Non-ISO Feature.
Initialization of M_CAN for version >= 3.1.x:
* TX FIFO of M_CAN is used to transmit frames. The driver does not need to
stop the tx queue after each frame sent.
* Initialization of TX Event FIFO is added.
* NON-ISO is fixed for all M_CAN versions < 3.2.x. Version 3.2.x _can_ have
the NISO (Non-ISO) bit which can switch the mode of the M_CAN to Non-ISO
mode. This bit does not have to be writeable. Therefore it is checked.
If it is writable Non-ISO support is added to the controllers supported
CAN modes.
New Functions:
* Function to check the Core Release version. The read value determines the
behaviour of the driver.
* Function to check if the NISO bit for version >= 3.2.x is implemented.

This patch adds the support of the PCAN-PCI Express FD boards made
by PEAK-System, for computers using the PCI Express slot.
The PCAN-PCI Express FD has one or two CAN FD channels, depending
on the model. A galvanic isolation of the CAN ports protects
the electronics of the card and the respective computer against
disturbances of up to 500 Volts. The PCAN-PCI Express FD can be operated
with ambient temperatures in a range of -40 to +85 °C.
Such boards run an extented version of the CAN-FD IP running into USB
CAN-FD interfaces from PEAK-System, so this patch adds several new commands
and their corresponding data types to the PEAK CAN-FD common definitions
header file too.

Tx napi mode increases the rate of transmit interrupts. Suppress some
by masking interrupts while more packets are expected. The interrupts

Convert virtio-net to a standard napi tx completion path. This enables
better TCP pacing using TCP small queues and increases single stream
throughput.
The virtio-net driver currently cleans tx descriptors on transmission
of new packets in ndo_start_xmit. Latency depends on new traffic, so
is unbounded. To avoid deadlock when a socket reaches its snd limit,
packets are orphaned on tranmission. This breaks socket backpressure,
including TSQ.
Napi increases the number of interrupts generated compared to the
current model, which keeps interrupts disabled as long as the ring
has enough free descriptors. Keep tx napi optional and disabled for
now. Follow-on patches will reduce the interrupt cost.
