Help text

This option adds a `CHECKSUM' target, which can be used in the iptables mangle table.

You can use this target to compute and fill in the checksum in a packet that lacks a checksum. This is particularly useful, if you need to work around old applications such as dhcp clients, that do not work well with checksum offloads, but don't want to disable checksum offload in your device.

To compile it as a module, choose M here. If unsure, say N.
