re-add $ipv6_enable support for backward compatibility. From
UPDATING:
1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF
for IPv4. For aliases, $ifconfig_IF_aliasN should be used.
Note that both variables need the "inet6" keyword at the head.
Do not set $ipv6_network_interfaces manually if you do not
understand what you are doing. It is not needed in most cases.
$ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but
they are obsolete.
2. $ipv6_enable is obsolete. Use $ipv6_prefer and/or
"inet6 accept_rtadv" keyword in ifconfig(8) instead.
If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and
all configured interfaces have "inet6 accept_rtadv" in the
$ifconfig_IF_ipv6. These are for backward compatibility.
3. A new variable $ipv6_prefer has been added. If NO, IPv6
functionality of interfaces with no corresponding
$ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag,
and the default address selection policy of ip6addrctl(8)
is the IPv4-preferred one (see rc.d/ip6addrctl for more details).
Note that if you want to configure IPv6 functionality on the
disabled interfaces after boot, first you need to clear the flag by
using ifconfig(8) like:
ifconfig em0 inet6 -ifdisabled
If YES, the default address selection policy is set as
IPv6-preferred.
The default value of $ipv6_prefer is NO.
4. If your system need to receive Router Advertisement messages,
define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8)
scripts automatically invoke rtsol(8) when the interface becomes
UP. The Router Advertisement messages are used for SLAAC
(State-Less Address AutoConfiguration).
- Add rc.d/stf and rc.d/faith for stf(4) and faith(4).
- Remove rc.d/auto_linklocal and rc.d/network_ipv6.
- Move rc.d/sysctl to just before FILESYSTEMS because rc.d/netif
depends on some sysctl variables.

rtsol_interface gets reset to "yes" each time through the loop, but
rtsol_available does not. If a user has lo0 first in their list of
interfaces rtsol_available will get set to "no" the first time through
the loop and subsequent interfaces will not get rtsol'ed when they should.
Therefore change the conditional for the is_wired() test to _interface.

gets ported back to RELENG_7.

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.
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.

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.

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.

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.

Using "list_network_interfaces all" resulted in using

new name is in $network_interfaces) or after (if the old name is in

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.)
