the interface name of interfaces that were configured.
This change has the added benefit that ifn_start() and
ifn_stop() in network.subr no longer write to standard output.
Whether to output and what to output is now handled entirely
in rc.d/netif.
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.
interface is an IPv6 interface.
Use this method to decide if we should attempt to configure an interface
with an IPv6 address in pccard_ether. The mechanism pccard_ether uses
to do this is unsuited to the task because it assumes the list of
interfaces it is passed is the full list of IPv6 interfaces and makes
decissions based on that. This is at least a step in the right
direction and is probably about as much as we can MFC safely.

now run on any interface.
- Add a new ifconfig_<ifn> keyword, NOAUTO which prevents configuration
of an interface at boot or via /etc/pccard_ether. This allows
/etc/rc.d/netif to be used to start and stop an interface on a purely
manual basis. The decision to affect pccard_ether may be revisited at
a later date.

way interfaces are configured. Some key points:
- At startup, all interfaces are configured through /etc/rc.d/netif.
- ifconfig_<if> variables my now mix real ifconfig commands the with
DHCP and WPA directives. For example, this allows media
configuration prior to running dhclient.
- /etc/rc.d/dhclient is not run at startup except by netif to start
dhclient on specific interfaces.
- /etc/pccard_ether calls "/etc/rc.d/netif start <if>" to do most of
it's work.
- /etc/pccard_ether no longer takes additional arguments to pass to
ifconfig. Instead, ifconfig_<if> variables are now honored in favor
of pccard_ifconfig when available.
- /etc/pccard_ether will only run on interfaces specified in
removable_interfaces, even if pccard_ifconfig is set.
and so the fix committed in r1.42 was not quite correct for the case
where there are two or more DHCP consuming removable interfaces - dhclient
must be restarted so that the other interfaces continue to function
correctly.

- If there was an exiting dhclient running on the same interface as the
new iface that left and returned then dhclient would be told to use the
same interface twice. Dhclient would fail and exit after getting
confused. Use "sort -u" on them to ensure no duplicates.
This is a mostly a race condition on suspend and resume and how things
happen to occur.
- Check for netmask being set on an interface rather then up. An interface
can be up but not configured.

Improve the dhcp handling of pccard_ether.
There are now many configurations which have a NIC on board and
cardbus slots too. If a dhclient was already running on the internal
NIC, the user was forced to kill a running dhclient manually.
If now a pccard is included at startup time, /etc/rc.d/dhclient
start does include it into the startup list for dhcp devices.
That means you can now do dhcp on the internal and the pccard devices
at the same time. If the card is plugged in later, a running dhclient
(working for the internal interface only) is killed, and restarted,
but the interface name of the new pccard is added to the internal
name. After removal, /etc/rc.d/dhclient is started again. This
script does nothing if there are no devices in /etc/rc.conf
This is only a workaround for a well known problem. After we have
a dhcp client which handles device adding and removal, it will go
away.
dhclient and pccard_ether, introduce the concept of a "settle time" to
pccard_ether with the new pccard_ether_delay variable. Defaults to 5
seconds, which is enough time for the ed driver to finish its
autoconfiguration for newer Linksys based cards. This also can
eliminate the ed0: timeout messages that happen at startup as well.
