12config CAN_SLCAN
13 tristate "Serial / USB serial CAN Adaptors (slcan)"
14 depends on TTY
15 ---help---
16 CAN driver for several 'low cost' CAN interfaces that are attached
17 via serial lines or via USB-to-serial adapters using the LAWICEL
18 ASCII protocol. The driver implements the tty linediscipline N_SLCAN.
19
20 As only the sending and receiving of CAN frames is implemented, this
21 driver should work with the (serial/USB) CAN hardware from:
22 www.canusb.com / www.can232.com / www.mictronics.de / www.canhack.de
23
24 Userspace tools to attach the SLCAN line discipline (slcan_attach,
25 slcand) can be found in the can-utils at the SocketCAN SVN, see
26 http://developer.berlios.de/projects/socketcan for details.
27
28 The slcan driver supports up to 10 CAN netdevices by default which
29 can be changed by the 'maxdev=xx' module option. This driver can
30 also be built as a module. If so, the module will be called slcan.

47 bit-rate specified via Netlink argument "bitrate" when the device
48 get started. This works fine for the most common CAN controllers
49 with standard bit-rates but may fail for exotic bit-rates or CAN
50 source clock frequencies. Disabling saves some space, but then the
51 bit-timing parameters must be specified directly using the Netlink
52 arguments "tq", "prop_seg", "phase_seg1", "phase_seg2" and "sjw".

13config CAN_VXCAN
14 tristate "Virtual CAN Tunnel (vxcan)"
15 ---help---
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.
