Usage Information
This command disables the hop field increments when boot requests are relayed to
a DHCP server through the system. If the incoming boot request already has a
non-zero hops field, the message is relayed with the same value for hops.
However, the message is discarded if the hops field exceeds 16, to comply with the
relay agent behavior specified in RFC 1542.
