+          Support for CAN cards from Softing Gmbh & some cards
+          from Vector Gmbh.
+          Softing Gmbh CAN cards come with 1 or 2 physical busses.
+          Those cards typically use Dual Port RAM to communicate
+          with the host CPU. The interface is then identical for PCI
+          and PCMCIA cards. This driver operates on a platform device,
+          which has been created by softing_cs or softing_pci driver.
+          Warning:
+          The API of the card does not allow fine control per bus, but
+          controls the 2 busses on the card together.
+          As such, some actions (start/stop/busoff recovery) on 1 bus
+          must bring down the other bus too temporarily.

+          firmware version 4.6 (softing-fw-4.6-binaries.tar.gz)
