The driver can allow the user to configure whether the CRC aka the FCS (Frame Check Sequence) is DMA'd to the host as part of the receive buffer. The driver usually wants this feature disabled so that the hardware checks the FCS and strips it in order to save PCI bandwidth. Control the reception of FCS to the host using the command: ethtool -K eth0 rx-fcs <on|off> The default shown in ethtool -k eth0 | grep fcs; should be "off", as the hardware will drop any frame with a bad checksum, and DMA of the checksum is useless overhead especially for small packets. Testing Hints: test the FCS/CRC arrives with received packets using tcpdump -nnpi eth0 -xxxx and it should show crc data as the last 4 bytes of the packet. Can also use wireshark to turn on CRC checking and check the data is correct.
