version 0.6.16

• ifreload: segfault fix to require argument for --timeout option
• client/nanny: initial handing of link-detection/require-link and
  timeout control flags (LINK_REQUIRED, LINK_READY_WAIT variables in
  suse ifcfg) to continue setup without ready link when requested in
  the config or based on device requirements (bsc#911562,bsc#914792).
• client/nanny: wait for event ACKs from wickedd instead to continue
  on successful request results where possible, to minimize the risk
  of an event backlog (bsc#905421).
• client/nanny: fsm timer and cleanup related fixes and improvements,
  fix to use "device-setup" (MAC, bond/bridge options, ...) as state
  name instead of "device-up" and use "device-up" as state when the
  device/link is administratively set UP. Separated waitLinkUp method
  to wait for link/carrier from linkUp setting it administratively UP.
• wickedd: fix to handle automatically created dummy0 interface
• wireless: consider auth-proto parameter (wpa1|wpa2) (bsc#911299)
• ipv6: add accept-dad sysctl support, fix accept-ra constants
• dhcp4: do not set/query mtu if set in the config (bsc#904323)
• dhcp4: limit MTU to be lower-equal 576 as before
• dhcp4: completed user-class option support permitting an rfc3004
  formatted option or as non-rfc, but widely used string (bsc#909307)
