Hi,
we currently developing our own socketcan driver and we have the
requirement to auto detect the baud rate at load time. Our HW is
supporting this but it seems this behavior is not configurable via IP
tools. Maybe I am wrong but has anyone an suggestion to do this? We
thought to use baud rate 0 to detect this but this is obviously not
allowed.
Thanks,
Sandro

Kernel space support for bitrate detection is not available or
implemented. But software driven bitrate detection should be possible
from user space by using the listen only mode. What hardware are you
speaking about? How does the hardware do the bitrate detection?
