Title:
  ifup fails on IPv6 static interface with alias

Status in “ifupdown” package in Ubuntu:
  Confirmed

Bug description:
  ifup doesn't trim alias portion of interface from sysctl when
  configuring IPv6 static addresses:

      # ifup eth0.4000:ucarp
       * Setting up iSCSI targets
         ...done.
      ssh stop/waiting
      ssh start/running, process 23415
      error: "net.ipv6.conf.eth0/4000:ucarp.autoconf" is an unknown key
      Failed to bring up eth0.4000:ucarp.

  /etc/network/interfaces:

      iface eth0.4000:ucarp inet6 static
        address 2001:db8::7006
        netmask 64

  Note: I'm running uCARP on the IPv4 address family, and expecting it
  to manage IPv6 address as well via `ifup $IFACE:ucarp` in
  /usr/share/ucarp/vip-up .

  I've tested with /sbin/ifup version 0.7.47.2ubuntu4 copied from a
  Trusty host and it works fine.
