Message:

Return the default TX and RX hardware checksum for the Cadence driver to off.

The hardware support does not seem to work with qemu. The support can be
enabled with ifconfig or via ioctl on real hardware to get the
performance boost.

     1084=== Cadence ===
     1085
     1086The cadence driver works on the Xilinx Zynq platform. The hardware checksum
     1087support works on real hardware but does not seem to be supported on qemu
     1088therefore the default state is disabled and it can be enabled from the shell
     1089with:
     1090
     1091  # ifconfig cgem0 rxcsum txcsum
     1092
     1093or with an ioctl call to the network interface driver with SIOCSIFCAP and the
     1094mask IFCAP_TXCSUM and IFCAP_RXCSUM set.
