you can refer to below example for RXFIFO usage within SDK
Example S32K144 FlexCAN RXFIFO DMA S32DS.ARM.2018.R1
But the RXFIFO itself does not help you to receive all IDs, matching is also done over RXFIFO ID filter table. If you want to receive all IDs you need to clear respective mask acceptance registers, so the receive ID is then don't care.
