The total number of frames transmitted on the port with a CRC error. Such a frame:
For port0 this statistics location (CPSW_STAT0_TXDROP) counts the number of drops to the host due to a memory protect error, or due to a cut-thru packet having an error on reception but was forwarded with the error. The Ethernet port receive error could be long, CRC, jabber, or code. For Ethernet ports, the receive error could be the same but the packet is transmitted with at least one byte of the actual outgoing packet CRC inverted to indicate the error.
A nonzero CPSW3_CPSW_NU_CPSW_NU_STAT_TXDEFERREDFRAMES_k value should be subtracted from the CPSW3_CPSW_NU_CPSW_NU_STAT_TXGOODFRAMES_k value to obtain the actual good frames value (the good frames statistic also increments on a transmitted CRC error).
