|  | default N | 
|  | ---help--- | 
|  | Similar to the network loopback devices, vcan offers a | 
|  | virtual local CAN interface. | 
|  |  | 
|  | This driver can also be built as a module.  If so, the module | 
|  | will be called vcan. |

|  | depends on CAN | 
|  | default Y | 
|  | ---help--- | 
|  | Enables the common framework for platform CAN drivers with Netlink | 
|  | support. This is the standard library for CAN drivers. | 
|  | If unsure, say Y. |

|  | config CAN_CALC_BITTIMING | 
|  | bool "CAN bit-timing calculation" | 
|  | depends on CAN_DEV | 
|  | default Y | 
|  | ---help--- | 
|  | If enabled, CAN bit-timing parameters will be calculated for the | 
|  | bit-rate specified via Netlink argument "bitrate" when the device | 
|  | get started. This works fine for the most common CAN controllers | 
|  | with standard bit-rates but may fail for exotic bit-rates or CAN | 
|  | source clock frequencies. Disabling saves some space, but then the | 
|  | bit-timing parameters must be specified directly using the Netlink | 
|  | arguments "tq", "prop_seg", "phase_seg1", "phase_seg2" and "sjw". | 
|  | If unsure, say Y. |
