We have a number of checksum the FCS (Frame Checksum) is normally done by the NIC plus FCS errors normally do not transfer the frame into memory. The other Checksums UDP, IP, TCP are done in hardware and software depending on the NIC being used. Need to read the docs for the NIC and then look at the config or setup of the RX/TX for that NIC in the example applications.
