For Socket-CAN, this driver is supposed to support all PLX PCI based
boards including the esd CAN PCI cards and also the IXXAT PCI board (not
yet done, though). The RTCAN driver xeno_can_esd_pci is a *dedicated*
driver for that card without generic support for the PLX PCI chips.
Extending it makes little sense. The question is if we want to drop
xeno_can_esd_pci and xeno_can_ixxat_pci.
