can: esd: acc_start_xmit(): use can_dev_dropped_skb() instead of can_dropped_invalid_skb()
...
In addition to can_dropped_invalid_skb(), the helper function
can_dev_dropped_skb() checks whether the device is in listen-only mode and
discards the skb accordingly.
Replace can_dropped_invalid_skb() by can_dev_dropped_skb() to also drop
skbs in for listen-only mode.

can: esd_402_pci: Add support for one-shot mode
...
This patch adds support for one-shot mode. In this mode there happens no
automatic retransmission in the case of an arbitration lost error or on
any bus error.

can: esd_402_pci: Rename esdACC CTRL register macros
...
Rename macros to use for esdACC CTRL register access to match the
internal documentation and to make the macro prefix consistent.
- ACC_CORE_OF_CTRL_MODE -> ACC_CORE_OF_CTRL
Makes the name match the documentation.
- ACC_REG_CONTROL_MASK_MODE_ -> ACC_REG_CTRL_MASK_
ACC_REG_CONTROL_MASK_ -> ACC_REG_CTRL_MASK_
Makes the prefix consistent for macros describing masks in the same
register (CTRL).

can: esd: add support for esd GmbH PCIe/402 CAN interface family
...
This patch adds support for the PCI based PCIe/402 CAN interface family
from esd GmbH that is available with various form factors
(https://esd.eu/en/products/402-series-can-interfaces ).
All boards utilize a FPGA based CAN controller solution developed
by esd (esdACC). For more information on the esdACC see
https://esd.eu/en/products/esdacc .
This driver detects all available CAN interface board variants of
the family but atm. operates the CAN-FD capable devices in
Classic-CAN mode only! A later patch will introduce the CAN-FD
functionality in this driver.
