Usage
Information
This command disables the incrementing of the hops field 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.
