   1 pppd: Allow specifying ipv6-up and ipv6-down scripts
   2
   3 This patch implements the "ipv6-up-script" and "ipv6-down-script" options
   4 which allow to specify the path of the ipv6-up and ipv6-down scripts to call.
   5
   6 These options default to _PATH_IPV6UP and _PATH_IPV6DOWN to retain the
   7 existing behaviour.
   8
   9 The patch originated from the Debian project.
