          will be called vcan.

+         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.
