By default network-scripts will set `accept_ra` only if $IPV6_AUTOCONF is
set to `yes`. If you don't want SLAAC addresses but do want to accept RA,
then set this to `yes`. Defaults to `no`.

+ Without this option, or if it is 'no'/'0', and DHCPV6C=yes,
+ 'dhclient -6' is run for the interface in "one-shot" mode; if the
+ DHCPv6 server does not respond for a configurable timeout, then
+ 'dhclient -6' exits and the interface is not brought up -
+ the '-1' option is given to 'dhclient -6'.
+ If PERSISTENT_DHCLIENT_IPV6=yes, then dhclient will keep on trying
+ to contact the DHCPv6 server when it does not respond - no '-1'
+ option is given to 'dhclienti -6'.
Special configuration options for multi-homed hosts etc.
