9ccb29637SOliver Hartkopp	  Similar to the network loopback devices, vcan offers a
10ccb29637SOliver Hartkopp	  virtual local CAN interface.
11ccb29637SOliver Hartkopp
12ccb29637SOliver Hartkopp	  This driver can also be built as a module.  If so, the module
13ccb29637SOliver Hartkopp	  will be called vcan.

2039549eefSWolfgang Grandegger	  Enables the common framework for platform CAN drivers with Netlink
2139549eefSWolfgang Grandegger	  support. This is the standard library for CAN drivers.
2239549eefSWolfgang Grandegger	  If unsure, say Y.

2839549eefSWolfgang Grandegger	---help---
2939549eefSWolfgang Grandegger	  If enabled, CAN bit-timing parameters will be calculated for the
3039549eefSWolfgang Grandegger	  bit-rate specified via Netlink argument "bitrate" when the device
3139549eefSWolfgang Grandegger	  get started. This works fine for the most common CAN controllers
3239549eefSWolfgang Grandegger	  with standard bit-rates but may fail for exotic bit-rates or CAN
3339549eefSWolfgang Grandegger	  source clock frequencies. Disabling saves some space, but then the
3439549eefSWolfgang Grandegger	  bit-timing parameters must be specified directly using the Netlink
3539549eefSWolfgang Grandegger	  arguments "tq", "prop_seg", "phase_seg1", "phase_seg2" and "sjw".
3639549eefSWolfgang Grandegger	  If unsure, say Y.

43ccb29637SOliver Hartkopp	  Say Y here if you want the CAN device drivers to produce a bunch of
44ccb29637SOliver Hartkopp	  debug messages to the system log.  Select this if you are having
45ccb29637SOliver Hartkopp	  a problem with CAN support and want to see more of what is going
46ccb29637SOliver Hartkopp	  on.
