The driver was suggested for deletion as it implements a subset of the netdev trigger. It's in the way for further cleanups in the trigger code but doesn't get an Ack by someone who can actually test and confirm that the netdev trigger works for can devices. So marking as broken to get forward with the cleanups.

config CAN_VCAN
|
|
tristate "Virtual Local CAN Interface (vcan)"
|
|
---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.
|
|
|
|
config CAN_VXCAN
|
|
tristate "Virtual CAN Tunnel (vxcan)"
|
|
---help---
|
|
Similar to the virtual ethernet driver veth, vxcan implements a
|
|
local CAN traffic tunnel between two virtual CAN network devices.
|
|
When creating a vxcan, two vxcan devices are created as pair.
|
|
When one end receives the packet it appears on its pair and vice
|
|
versa. The vxcan can be used for cross namespace communication.
|
|
|
|
In opposite to vcan loopback devices the vxcan only forwards CAN
|
|
frames to its pair and does *not* provide a local echo of sent
|
|
CAN frames. To disable a potential echo in af_can.c the vxcan driver
|
|
announces IFF_ECHO in the interface flags. To have a clean start
|
|
in each namespace the CAN GW hop counter is set to zero.
|
|
|
|
This driver can also be built as a module. If so, the module
|
|
will be called vxcan.
|
|

config CAN_SLCAN
|
|
tristate "Serial / USB serial CAN Adaptors (slcan)"
|

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

---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.
