      Description

      RCF 5227 section 2.1.1 states:

      "A host implementing this specification MUST take precautions to limit
      the rate at which it probes for new candidate addresses: if the host
      experiences MAX_CONFLICTS or more address conflicts on a given
      interface, then the host MUST limit the rate at which it probes for
      new addresses on this interface to no more than one attempted new
      address per RATE_LIMIT_INTERVAL. "

      MAX_CONFLICTS = 10
      RATE_LIMIT_INTERVAL = 60 seconds

      Currently the stack does not comply with this, since it tries to get a valid IP address in an endless loop.
