Usage
Information
This command disables the incrementing of the hops field when boot requests are
relayed to a DHCP server through Dell Networking OS. 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.
