This option sets the sender checksum coverage.
A value of zero indicates that all sent packets will have
full checksum coverage.
A value of 8 to 65535 limits the checksum coverage of all sent packets
to the value given.
This option is the receiver-side analogue.
A value of zero instructs the kernel to drop all received packets
not having full checksum coverage.
A value of 8 to 65535 instructs the kernel to drop all received
packets with a partial checksum coverage smaller than the value specified.
A socket operation may fail with one of the following errors returned:
