The devices are meant to be under the "Device Drivers" category of the
menuconfig. The CAN subsystem is currently one of the rare exception
with all of its devices under the "Networking support" category.
The CAN_DEV menuentry gets moved to fix this discrepancy. The CAN menu
is added just before MCTP in order to be consistent with the current
order under the "Networking support" menu.
A dependency on CAN is added to CAN_DEV so that the CAN devices only
show up if the CAN subsystem is enabled.

Only a few drivers rely on the CAN rx offload framework (as of the
writing of this patch, only four: flexcan, m_can, mcp251xfd and
ti_hecc). Split it out of can-dev and add a new config symbol:
CAN_RX_OFFLOAD.
The drivers relying on CAN rx offload are in different sub
folders. Make CAN_RX_OFFLOAD an hidden option and tag all the drivers
depending on that feature with "select CAN_RX_OFFLOAD" so that the
option gets automatically enabled if and only if one of those drivers
is chosen.

The canonical way to select or deselect an object during compilation
is to use this pattern in the relevant Makefile:
bar-$(CONFIG_FOO) := foo.o
bittiming.c instead uses some #ifdef CONFIG_CAN_CALC_BITTIMG.
Create a new file named calc_bittiming.c with all the functions which
are conditionally compiled with CONFIG_CAN_CALC_BITTIMG and modify the
Makefile according to above pattern.

In the next patches, the software/virtual drivers (slcan, v(x)can)
will depend on drivers/net/can/dev/skb.o.
This patch changes the scope of the can-dev module to include the
above mentioned drivers.
To do so, we reuse the menu "CAN Device Drivers" and turn it into a
configmenu using the config symbol CAN_DEV (which we released in
previous patch). Also, add a description to this new CAN_DEV
menuconfig.
The symbol CAN_DEV now only triggers the build of skb.o. For this
reasons, all the macros from linux/module.h are deported from
drivers/net/can/dev/dev.c to drivers/net/can/dev/skb.c.
Finally, drivers/net/can/dev/Makefile is adjusted accordingly.

In the next patches, the scope of the can-dev module will grow to
engloble the software/virtual drivers (slcan, v(x)can). To this
extent, release CAN_DEV by renaming it into CAN_NETLINK. The config
symbol CAN_DEV will be reused to cover this extended scope.
The rationale for the name CAN_NETLINK is that netlink is the
predominant feature added here.
The current description only mentions platform drivers despite the
fact that this symbol is also required by "normal" devices (e.g. USB
or PCI) which do not fall under the platform devices category. The
description is updated accordingly to fix this gap.

do_set_bittiming callback
Usually CAN devices support configurable bit rates. The limits are
defined by struct can_priv::bittiming_const. Another way is to
implement the struct can_priv::do_set_bittiming callback.
If the bit rate is configured via netlink, the can_changelink()
function checks that either can_priv::bittiming_const or struct
can_priv::do_set_bittiming is implemented.
In commit 431af779256c ("can: dev: add CAN interface API for fixed
bitrates") an API for configuring bit rates on CAN interfaces that
only support fixed bit rates was added. The supported bit rates are
defined by struct can_priv::bitrate_const.
However the above mentioned commit forgot to add the struct
can_priv::bitrate_const to the check in can_changelink().
In order to avoid to implement a no-op can_priv::do_set_bittiming
callback on devices with fixed bit rates, extend the check in
can_changelink() accordingly.

This patch adds Transmitter Delay Compensation (TDC) feature support.
In the case of higher measured loop delay with higher bit rates, bit
stuff errors are observed. Enabling the TDC feature in CAN-FD
controllers will compensate for the measured loop delay in the receive
path.

nfp_net_sriov_check is added in nfp_app_get_vf_config which intends
to ensure ivi->vlan_proto and ivi->max_tx_rate/min_tx_rate can be
read from VF config table only when firmware supports corresponding
capability.
However, "nfp_app_get_vf_config" can be called by commands like
"ip a", "ip link set $DEV up" and "ip link set $DEV vf $NUM vlan
$param" (with VF). When using commands above, many warnings
"ndo_set_vf_<cap_x> not supported" would appear if firmware doesn't
support VF rate limit and 802.1ad VLAN assingment. If more VFs are
created, things could get worse.
Thus, this patch add an extra bool parameter for nfp_net_sriov_check
to enable/disable the cap check warning report. Unnecessary warnings
in nfp_app_get_vf_config can be avoided. Valid warnings in kinds of
vf setting function can be reserved.

gcc-12 started warning about 'tracker' being used uninitialized:

drivers/net/ethernet/mellanox/mlx5/core/lag/lag.c:786:28: warning: ‘tracker’ is used uninitialized [-Wuninitialized]
786 | struct lag_tracker tracker;
| ^~~~~~~
which seems to be because it doesn't track how the use (and
initialization) is bound by the 'do_bond' flag.
But admittedly that 'do_bond' usage is fairly complicated, and involves
passing it around as an argument to helper functions, so it's somewhat
understandable that gcc doesn't see how that all works.
This function could be rewritten to make the use of that tracker
variable more obviously safe, but for now I'm just adding the forced
initialization of it.

The code for retrieving the statistics from the device is taken from the
out-of-tree driver. The feature was introduced with version 2.0.75.7,
so the diff between this version and the previous version 2.0.72.4 was
used to identify required changes. The export via ethtool is omitted in
favor of using the standard ndo_get_vf_stats interface.
Per-VF statistics can now be printed, for instance, via
ip --statistics link show dev eth0

With all vmxnet3 version 7 changes incorporated in the vmxnet3 driver,
the driver can configure emulation to run at vmxnet3 version 7, provided
the emulation advertises support for version 7.

Till vmxnet3 version 6, om field of transmit descriptor was used
to indicate encapsulated offload packet and msscof was used to
indirectly indicate TSO/CSO. From version 7 and later, ext1 field
will be used to indicate whether packet is encapsulated or not and
om fields will continue to indicate if the packet is TSO or CSO.

Currently, vmxnet3 does not have a limit on number of descriptors
used for a TSO packet. However, with UPT, for hardware performance
reasons, this patch limits the number of transmit descriptors to 24
for a TSO packet.

This patch adds a new command to set ring buffer sizes. This is
required to pass the buffer size information to passthrough devices.
For performance reasons, with version7 and later, ring1 will contain
only mtu size buffers (bound to 3K). Packets > 3K will use both ring1
and ring2.
Also, ring sizes are round down to power of 2 and ring2 default
size is increased to 512.

Currently, vmxnet3 processes rx completions in-order i.e. no
out of order completion descriptor is expected. With UPT, if
hardware supports LRO, then hardware can report out of order
rx completions. This patch enhances vmxnet3 to add this support.
This supports gets effective only when the corresponding feature
bit is set.
Also, minor enhancements are done for performance.

For vmxnet3 to work in UPT mode, the BAR sizes have been increased.
The PT page has been extended to 2 pages and also includes OOB pages
as a part of PT BAR. This patch enhances vmxnet3 to use appropriate
BAR offsets based on the capability registered. To use new offsets,
VMXNET3_CAP_LARGE_BAR needs to be set by the device. If it is not set
then the device will use legacy PT page layout.

This patch enhances vmxnet3 to suuport capability registers which
allows it to enable features selectively. The DCR register tracks
the capabilities vmxnet3 device supports. The PTCR register states
the capabilities that the passthrough device supports.
With the help of these registers, vmxnet3 can enable only those
features which the passthrough device supoprts. This allows
smooth trasition to Uniform-Passthrough (UPT) mode if the virtual
nic requests it. If PTCR register returns nothing or error it means
UPT is not being requested and vnic will continue in emulation mode.

see warning:
| drivers/net/ethernet/amd/xgbe/xgbe-drv.c:2787:43: warning: format specifies

| netdev_dbg(netdev, "Protocol: %#06hx\n", ntohs(eth->h_proto));
| ~~~~~~ ^~~~~~~~~~~~~~~~~~~
Variadic functions (printf-like) undergo default argument promotion.
Documentation/core-api/printk-formats.rst specifically recommends
using the promoted-to-type's format flag.
Also, as per C11 6.3.1.1:
(https://www.open-std.org/jtc1/sc22/wg14/www/docs/n1548.pdf)
`If an int can represent all values of the original type ..., the
value is converted to an int; otherwise, it is converted to an
unsigned int. These are called the integer promotions.`
Since the argument is a u16 it will get promoted to an int and thus it is
most accurate to use the %x format specifier here. It should be noted that the
`#06` formatting sugar does not alter the promotion rules.
