slower-ramping backoff.

Quagga 1.1.0

  This is a release with a number of new features, and many bug fixes.
  Notably:

    Greatly improved nexthop resolution for recursive routes. (Cumulus)
    Event driven nexthop resolution for BGP (Cumulus)
    Route tags support (Piotr Chytła, Packet Consulting)
    Transport of TE related metrics over OSPF, IS-IS (Olivier Dugeon, Orange)
    IPv6 Multipath for zebra and BGP (Ayan Banerjee, Cumulus)

  This release also changed the default of 'link-detect' state,
  controlling whether zebra will respond to link-state events and
  consider an interface to be down when link is down. To retain
  current the behavior save your config before updating, otherwise
  remove the 'link-detect' flag from your config prior to
  updating. There is also a new global 'default link-detect (on|off)'
  flag to configure the global default.
