Cool! But, the Teensy 4 CPU technically has three CAN buses in hardware, not two. The third is CAN-FD capable. Are there any plans to support this?

FlexCAN3 is not available through the HAL, not even for CAN 2.0B functions. There's also no CANFD support in the proposed driver.

If you have a need for that third CAN network or CANFD, could you leave a note on the upstream PR? It'll reach a wider audience.
