Usage 
information
The description of this flag from RFC 2461 (http://tools.ietf.org/html/rfc2461) is: M: 1-bit 
“Managed address configuration” flag. When set, hosts use the administered (stateful) 
protocol for address autoconfiguration in addition to any addresses autoconfigured using 
stateless address autoconfiguration. The use of this flag is described in: Thomson, S. and T. 
Narten, “IPv6 Address Autoconfiguration”, RFC 2462, December 1998.
