13 For most flexcan IP cores the driver supports 2 RX modes:
15 - FIFO
16 - mailbox
20 configured for RX-FIFO mode.
22 The RX FIFO mode uses a hardware FIFO with a depth of 6 CAN frames,
23 while the mailbox mode uses a software FIFO with a depth of up to 62
24 CAN frames. With the help of the bigger buffer, the mailbox mode
28 cores come up in a mode where RTR reception is possible.
