CPPI port ingress packets can be passed in with or without a CRC. The ingress packet CRC type is indicated in the buffer descriptor word CRC_TYPE bit and can be Ethernet (or Castagnoli if $cppi_cast = 1). The packet CRC_TYPE can change from packet to packet if Castagnoli is supported ($cppi_cast = 1). The P0_RX_PASS_CRC_ERR bit in the CPSW Control register determines if ingress packets with CRC errors are passed or dropped. Passed packets with CRC errors will be transmitted on Ethernet egress with a CRC error.
