The tested 0bfd:0017 Kvaser Memorator Professional HS/HS FW 2.0.50 and
0bfd:0124 Kvaser Mini PCI Express 2xHS FW 4.18.778 do not seem to send
any unsolicited events when error counters decrease or when the device
transitions from ERROR_PASSIVE to ERROR_ACTIVE (or WARNING).
This causes the interface to e.g. indefinitely stay in the ERROR_PASSIVE
state.
Fix that by asking for chip state (inc. counters) event every 0.5 secs
when error counters are non-zero.
Since there are non-error-counter devices, also always poll in
ERROR_PASSIVE even if the counters show zero.

can: kvaser_usb_leaf: Fix TX queue out of sync after restart
The TX queue seems to be implicitly flushed by the hardware during
bus-off or bus-off recovery, but the driver does not reset the TX
bookkeeping.
Despite not resetting TX bookkeeping the driver still re-enables TX
queue unconditionally, leading to "cannot find free context" /
NETDEV_TX_BUSY errors if the TX queue was full at bus-off time.
Fix that by resetting TX bookkeeping on CAN restart.

can: kvaser_usb: advertise timestamping capabilities and add ioctl support
Currently, userland has no method to query which timestamping features
are supported by the kvaser_usb driver (aside maybe of getting RX
messages and observe whether or not hardware timestamps stay at zero).
The canonical way for a network driver to advertise what kind of
timestamping it supports is to implement
ethtool_ops::get_ts_info(). Here, we use the CAN specific
can_ethtool_op_get_ts_info_hwts() function to achieve this.
In addition, the driver currently does not support the hardware
timestamps ioctls. According to [1], SIOCSHWTSTAMP is "must" and
SIOCGHWTSTAMP is "should". This patch fills up that gap by
implementing net_device_ops::ndo_eth_ioctl() using the CAN specific
function can_eth_ioctl_hwts().

can: do not increase tx_bytes statistics for RTR frames
The actual payload length of the CAN Remote Transmission Request (RTR)
frames is always 0, i.e. no payload is transmitted on the wire.
However, those RTR frames still use the DLC to indicate the length of
the requested frame.
As such, net_device_stats::tx_bytes should not be increased when
sending RTR frames.
The function can_get_echo_skb() already returns the correct length,
even for RTR frames (c.f. [1]). However, for historical reasons, the
drivers do not use can_get_echo_skb()'s return value and instead, most
of them store a temporary length (or dlc) in some local structure or
array. Using the return value of can_get_echo_skb() solves the
issue. After doing this, such length/dlc fields become unused and so
this patch does the adequate cleaning when needed.
This patch fixes all the CAN drivers.
Finally, can_get_echo_skb() is decorated with the __must_check
attribute in order to force future drivers to correctly use its return
value (else the compiler would emit a warning).

can: kvaser_usb: kvaser_usb_leaf: fix CAN clock frequency regression
commit e6c80e601053ffdac5709f11ff3ec1e19ed05f7b upstream.
The firmware of M32C based Leaf devices expects bittiming parameters
calculated for 16MHz clock. Since we use the actual clock frequency of
the device, the device may end up with wrong bittiming parameters,
depending on user requested parameters.
This regression affects M32C based Leaf devices with non-16MHz clock.
Fixes: a8b513b824e4 ("can: kvaser_usb: get CAN clock frequency from device")
