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

a7f7f624 | 15 | help |
a8f820a3 OH |
16 | Similar to the virtual ethernet driver veth, vxcan implements a |
17 | local CAN traffic tunnel between two virtual CAN network devices. | |
18 | When creating a vxcan, two vxcan devices are created as pair. | |
19 | When one end receives the packet it appears on its pair and vice | |
20 | versa. The vxcan can be used for cross namespace communication. | |
21 | ||
22 | In opposite to vcan loopback devices the vxcan only forwards CAN | |
23 | frames to its pair and does *not* provide a local echo of sent | |
24 | CAN frames. To disable a potential echo in af_can.c the vxcan driver | |
25 | announces IFF_ECHO in the interface flags. To have a clean start | |
26 | in each namespace the CAN GW hop counter is set to zero. | |
27 | ||
28 | This driver can also be built as a module. If so, the module | |
29 | will be called vxcan. | |

35 | CAN driver for several 'low cost' CAN interfaces that are attached |
36 | via serial lines or via USB-to-serial adapters using the LAWICEL | |
37 | ASCII protocol. The driver implements the tty linediscipline N_SLCAN. | |
38 | ||
39 | As only the sending and receiving of CAN frames is implemented, this | |
40 | driver should work with the (serial/USB) CAN hardware from: | |
c128df73 | 41 | www.canusb.com / www.can232.com / www.mictronics.de / www.canhack.de |

43 | Userspace tools to attach the SLCAN line discipline (slcan_attach, | |

44 | slcand) can be found in the can-utils at the linux-can project, see |
45 | https://github.com/linux-can/can-utils for details. | |

47 | The slcan driver supports up to 10 CAN netdevices by default which | |
48 | can be changed by the 'maxdev=xx' module option. This driver can | |
49 | also be built as a module. If so, the module will be called slcan. | |

39549eef WG |
65 | If enabled, CAN bit-timing parameters will be calculated for the |
66 | bit-rate specified via Netlink argument "bitrate" when the device | |
67 | get started. This works fine for the most common CAN controllers | |
68 | with standard bit-rates but may fail for exotic bit-rates or CAN | |
69 | source clock frequencies. Disabling saves some space, but then the | |
70 | bit-timing parameters must be specified directly using the Netlink | |
71 | arguments "tq", "prop_seg", "phase_seg1", "phase_seg2" and "sjw". | |
72 | If unsure, say Y. | |
