The interface is then identical for PCI 11 and PCMCIA cards. This driver operates on a platform device, 12 which has been created by softing_cs or softing_pci driver. 13 Warning: 14 The API of the card does not allow fine control per bus, but 15 controls the 2 busses on the card together. 16 As such, some actions (start/stop/busoff recovery) on 1 bus 17 must bring down the other bus too temporarily. 18 19config CAN_SOFTING_CS 20 tristate "Softing Gmbh CAN pcmcia cards" 21 depends on PCMCIA 22 depends on CAN_SOFTING 23 help 24 Support for PCMCIA cards from Softing Gmbh & some cards 25 from Vector Gmbh. 26 You need firmware for these, which you can get at 27 http://developer.berlios.de/projects/socketcan/ 28 This version of the driver is written against 29 firmware version 4.6 (softing-fw-4.6-binaries.tar.gz) 30 In order to use the card as CAN device, you need the Softing generic 31 support too. 32
