  Log:
  Disable IPv6 configuration for interfaces in pccard_ether_start().
  
  After a change of devd.conf, devd(8) handles NIC attach/detach event
  by using /etc/pccard_ether with the interface name as the argument.
  This model does not work properly with IPv6 configuration because the
  implementation of IPv6 stateless auto-configuration in the FreeBSD
  rc.d scripts depends on whether there are any explicit configurations
  for interfaces or not.  It works this way: if no manual configuration,
  it will perform auto-configuration, but otherwise no
  auto-configuration will be performed.  So, this behavior can only be
  determined by all of the interfaces on a system, not a single one.
  For this reason, the network6_interface_setup() function called from
  the pccard_ether_start() does not work with a single interface name.
  And what is worse, this combination of devd.conf and
  pccard_ether_start() caused a bad side-effect that when
  ipv6_enable=YES, all of interfaces marked as DOWN would be UP
  unconditionally (and router solicitation was sent) just after devd(8)
  was invoked.  This should be fixed in a more sophisticated way.
