3a31a0cef3 Change the default value of synchronous_dhclient to NO.
To preserve the existing behavior of etc/rc.d/netif, add code to wait
up to if_up_delay seconds (30 seconds by default) for a default route to
be configured if there are any dhcp interfaces.  This should be extended
to test that the interface is actually up.

e44e0b612b Change wpa_supplicant to down the interface at the start of the init routine.
wpa_supplicant expects that it has exclusive access to the net80211 state so
when its starts poking in the WEP/WPA settings and the card is already
scanning it can cause net80211 to try and associate incorrectly with a
protected AP.

This is an inconvenience for firmware based cards such as iwi where it can be
sent an auth instruction with incomplete security info and cause a firmware
error.

Remove the 'ifconfig up' from network.subr since wpa_supplicant will
immediately down the interface again.

aa92e52181 Introduce a new method ipv6if which attemptes to figure out if an
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.

1f100dedee Commit the various network interface configutation updates I've been
working on.
  1) Make it possible to configure interfaces with certain characters in
     their names that aren't valid in shell variables.  Currently supported
     characters are ".-/+".  They are converted into '_' characters.
  2) Replace nearly all eval statements in network.subr with a new
     function get_if_var which substitues an interface name (after the
     translations above) for "IF" in a variable name.
  3) Fix list_net_interfaces() in the nodhcp case.
  4) Allow the administrator to specify if dhclient should be started
     when /etc/rc.d/netif configures the interface or only by devd.
     This can be set on both a per interface and system wide basis.

267072f91c Add a new configuration variable, ipv4_addrs_<ifn>, which adds one or
more IPv4 address from a ranged list in CIRD notation:

ipv4_addrs_ed0="192.168.0.1/24 192.168.1.1-5/28"

more toward a less IPv4 centric world.

ec73ff7b51 - Remove the removable_interfaces variable. /etc/pccard_ether will
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.

c724d1075b - Remove the pccard_ifconfig variable in favor of a new
ifconfig_DEFAULT variable.  Unlike pccard_ifconfig, ifconfig_DEFAULT
   applies to all interfaces that do not specify an ifconfig_<ifn>
   variable rather than just those listed in removable_interfaces.
 - Correct the list of interfaces when network_interfaces and
   removable_interfaces are both set by including removable_interfaces
   in the list of canidates.
 - When listing dhcp interfaces, include those with other ifconfig
   options so nat works.

5a3d620fb1 Support code for the OpenBSD dhclient. This significantly changes the
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.

68bef2dca5 Use "ifconfig -l" instead of "list_network_interfaces all" in
ifnet_rename() to support situations where rc.conf's $network_interfaces
variable is set to an explicit list of network interfaces (instead of
the default "auto").

Using "list_network_interfaces all" resulted in using
$network_interfaces for both interface _renaming_ and interface
_configuration_ which obviously cannot work either before (if the
new name is in $network_interfaces) or after (if the old name is in
$network_interfaces) renaming the interface.

2032b765e7 Avoid double appearing of cloned interfaces in the output
from list_net_interfaces() when network_interfaces=auto.

Rationale: Since the auto case is special, the lesser evil
had to be chosen among not adding cloned interfaces to
_tmplist or removing duplicates from _tmplist after adding
cloned interfaces.  Since list_net_interfaces() must not use
/usr/bin tools, the former "evil" appeared clearer and much
more efficient.  (See the PR audit trail for discussion.)

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.
