This patch adds support for the CAN FD controller found in Renesas R-Car
SoCs. The controller operates in CAN FD only mode by default.

CAN FD mode supports both Classical CAN & CAN FD frame formats. The
controller supports ISO 11898-1:2015 CAN FD format only.

This controller supports two channels and the driver can enable either
or both of the channels.

Driver uses Rx FIFOs (one per channel) for reception & Common FIFOs (one
per channel) for transmission. Rx filter rules are configured to the
minimum (one per channel) and it accepts Standard, Extended, Data &
Remote Frame combinations.

Note: There are few documentation errors in R-Car Gen3 Hardware User
Manual v0.5E with respect to CAN FD controller. They are listed below:

1. CAN FD interrupt numbers 29 & 30 are listed as per channel
interrupts. However, they are common to both channels (i.e.) they are
global and channel interrupts respectively.

2. CANFD clock is derived from PLL1. This is not documented.

3. CANFD clock is further divided by (1/2) within the CAN FD controller.
This is not documented.

4. The minimum value of NTSEG1 in RSCFDnCFDCmNCFG register is 2 Tq. It
is specified 4 Tq in the manual.

5. The maximum number of message RAM area the controller can use is 3584
bytes. It is specified 10752 bytes in the manual.

The programming API of the CAN_BCM depends on struct can_frame which is
given as array directly behind the bcm_msg_head structure. To follow this
schema for the CAN FD frames a new flag 'CAN_FD_FRAME' in the bcm_msg_head
flags indicates that the concatenated CAN frame structures behind the
bcm_msg_head are defined as struct canfd_frame.

This patch adds the support to handle CAN and CAN FD frames on a per BCM-op
base. Main changes:

- generally use struct canfd_frames instead if struct can_frames
- use canfd_frame.flags instead of can_frame.can_dlc for private BCM flags
- make all CAN frame sizes depending on the new CAN_FD_FRAME flags
- separate between CAN and CAN FD when sending/receiving frames

Due to the dependence of the CAN_FD_FRAME flag the former binary interface
for classic CAN frames remains stable.

This patch optimizes the calculation of the sample point. To understand what it
does have a look at the original implementation.

If there is a combination of timing parameters where both the bitrate and
sample point error are 0 the current implementation will find it.

However if the reference clock doesn't allow an optimal bitrate (this means the
bitrate error is always != 0) there might be several timing parameter
combinations having the same bitrate error. The original implementation will
allways choose the one with the highest brp. The actual sample point error
isn't taken into account.

This patch changes the algorithm to minimize the sample point error, too. Now a
brp/tseg combination is accepted as better if one of these condition are
fulfilled:
1) the bit rate error must be smaller, or
2) the bit rate error must be equal and
   the sample point error must be equal or smaller

If a smaller bit rate error is found the sample point error is reset. This
ensures that we first optimize for small bit rate error and then for small
sample point errors.

vmxnet3: upgrade to version 3

vmxnet3 emulation has recently added several new features which includes
support for new commands the driver can issue to emulation, change in
descriptor fields etc. This patch series extends the vmxnet3 driver to
leverage these new features.

Compatibility is maintained using existing vmxnet3 versioning mechanism as
follows:
 - new features added to vmxnet3 emulation are associated with new vmxnet3
   version viz. vmxnet3 version 3.
 - emulation advertises all the versions it supports to the driver.
 - during initialization, vmxnet3 driver picks the highest version number
 supported by both the emulation and the driver and configures emulation
 to run at that version.

In particular, following changes are introduced:

Patch 1:
  Some command definitions from previous vmxnet3 versions are
  missing. This patch adds those definitions before moving to vmxnet3
  version 3. It also fixes copyright info and maintained by.

Patch 2:
  This patch introduces generalized command interface which allows
  for easily adding new commands that vmxnet3 driver can issue to the
  emulation. Further patches in this series make use of this facility.

Patch 3:
  Transmit data ring buffer is used to copy packet headers or small
  packets. It is a fixed size buffer. This patch extends the driver to
  allow variable sized transmit data ring buffer.

Patch 4:
  This patch introduces receive data ring buffer - a set of small sized
  buffers that are always mapped by the emulation. This avoids memory
  mapping/unmapping overhead for small packets.

Patch 5:
  The vmxnet3 emulation supports a variety of coalescing modes. This patch
  extends vmxnet3 driver to allow querying and configuring these modes.

Patch 6:
  In vmxnet3 version 3, the emulation added support for the vmxnet3 driver
  to communicate information about the memory regions the driver will use
  for rx/tx buffers. This patch exposes related commands to the driver.

Patch 7:
  With all vmxnet3 version 3 changes incorporated in the vmxnet3 driver,
  with this patch, the driver can configure emulation to run at vmxnet3
  version 3.

Changes in v2:
 - v1 patch used special values of rx-usecs to differentiate between
 coalescing modes. v2 uses relevant fields in struct ethtool_coalesce
 to choose modes. Also, a new command VMXNET3_CMD_GET_COALESCE
 is introduced which allows driver to query the device for default
 coalescing configuration.

Changes in v3:
 - fix subject line to use vmxnet3: instead of Driver:Vmxnet3
 - resubmit when net-next is open

Changes in v4:
 - Address code review comments by Ben Hutchings: remove unnecessary memset
   from vmxnet3_get_coalesce.

Changes in v5:
 - Updated all the patches to add detailed commit messages.

In vmxnet3 version 3, the emulation added support for the vmxnet3 driver
to communicate information about the memory regions the driver will use
for rx/tx buffers. The driver can also indicate which rx/tx queue the
memory region is applicable for. If this information is communicated
to the emulation, the emulation will always keep these memory regions
mapped, thereby avoiding the mapping/unmapping overhead for every packet.

Currently, Linux vmxnet3 driver does not leverage this capability. The
feasibility of using this approach for the Linux vmxnet3 driver will be
investigated independently and if possible, will be part of a different
patch. This patch only exposes the emulation capability to the driver
(vmxnet3_defs.h is identical between the driver and the emulation).

vmxnet3 driver preallocates buffers for receiving packets and posts the
buffers to the emulation. In order to deliver a received packet to the
guest, the emulation must map buffer(s) and copy the packet into it.

To avoid this memory mapping overhead, this patch introduces the receive
data ring - a set of small sized buffers that are always mapped by
the emulation. If a packet fits into the receive data ring buffer, the
emulation delivers the packet via the receive data ring (which must be
copied by the guest driver), or else the usual receive path is used.

Receive Data Ring buffer length is configurable via ethtool -G ethX rx-mini

Shared memory is used to exchange information between the vmxnet3 driver
and the emulation. In order to request emulation to perform a task, the
driver first populates specific fields in this shared memory and then
issues corresponding command by writing to the command register(CMD). The
layout of the shared memory was defined by vmxnet3 version 1 and cannot
be extended for every new command without breaking backward compatibility.

To address this problem, in vmxnet3 version 3, the emulation repurposed
a reserved field in the shared memory to represent command information
instead. For new commands, the driver first populates the command
information field in the shared memory and then issues the command. The
emulation interprets the data written to the command information depending
on the type of the command. This patch exposes this capability to the driver.

The function set_features is called to configure network device features
on the hardware. If errors occur, the network device features should
reflect the changed hardware state and the function should return an
error in order to notify the user.

In case of an error, the current implementation does not necessarily
save the changed hardware state in the network device features before an
error is returned.

This patch improves error handling by saving features, that could be
changed, to the network device features before returning an error. If
the device is not running, an additional check in fix_features removes
features, that require hardware changes, before they are passed to
set_features. Thus, the corresponding check was removed in set_features.

network device features (vlan_features) indicate for each network device,
which capabilities can be used on VLAN devices, that are configured on the
respective base network device.

In the current qeth implementation, network device features are only set
for the base network devices and not for the VLAN devices. Thus, features
like TX checksum offloading cannot be used on VLAN devices.

This patch adds network device features to vlan_features, so they can be
