These are the CAN frames dropped by the socket, this means as Oliver
pointed out, that the candump fails to read the CAN frames fast enough
from the socket. How do you connect to the linux box with the c_can?
Where are the CAN frames printed to?
Dropped CAN frames by the hardware should be counted in the rx dropped
in ifconfig.
