4d84f49da4 Prevent unloading a kld for a driver that has subinterfaces (vlan and/or
wlan interfaces) from being automatically reloaded via devd shutdown
event handlers.
- Revert part of my previous changes to call ifn_stop on subinterfaces
  when an interface is detached.  It is better to destroy the interfaces
  first so that an 'ifconfig foo0.blah down' doesn't result in ifconfig
  auto-loading if_foo.ko.  The ifconfig command will not be invoked if
  foo0.blah is gone when ifn_stop() is called.  Furthermore, it is not
  necessary to explicitly invoke ifn_stop() after the subinterface is
  destroyed as devd will already do that.
- Pass -n to ifconfig when destroying interfaces so that destroying a
  cloned interface does not kldload any drivers.

8aa4c57946 Improve the handling of IPv6 configuration in rc.d. The ipv6_enable
and ipv6_ifconfig_<interface> options have already been deprecated,
these changes do not alter that.

With these changes any value set for ipv6_enable will emit a
warning. In order to avoid a POLA violation for the deprecation
of the option ipv6_enable=NO will still disable configuration
for all interfaces other than lo0. ipv6_enable=YES will not have
any effect, but will emit an additional warning. Support and
warnings for this option will be removed in FreeBSD 10.x.

Consistent with the current code, in order for IPv6 to be configured
on an interface (other than lo0) an ifconfig_<interface>_ipv6
option will have to be added to /etc/rc.conf[.local].

1. Clean up and minor optimizations for the following functions:
ifconfig_up (the ipv6 elements)
ipv6if
ipv6_autoconfif
get_if_var
_ifconfig_getargs
The cleanups generally were to move the "easy" tests earlier in the
functions, and consolidate duplicate code.

2. Stop overloading ipv6_prefer with the ability to disable IPv6
configuration.

3. Remove noafif() which was only ever called from ipv6_autoconfif.
Instead, simplify and integrate the tests into that function, and
convert the test to use is_wired_interface() instead of listing
wireless interfaces explicitly.

4. Integrate backwards compatibility for ipv6_ifconfig_<interface>
into _ifconfig_getargs. This dramatically simplifies the code in
all of the callers, and avoids a lot of other code duplication.

5. In rc.d/netoptions, add code for an ipv6_privacy option to use
RFC 4193 style pseudo-random addresses (this is what windows does
by default, FYI).

6. Add support for the [NO]RTADV options in ifconfig_getargs() and
ipv6_autoconfif(). In the latter, include support for the explicit
addition of [-]accept_rtadv in ifconfig_<interface>_ipv6 as is done
in the current code.

7. In rc.d/netif add a warning if $ipv6_enable is set, and remove
the set_rcvar_obsolete for it. Also remove the latter from
rc.d/ip6addrctl.

8. In /etc/defaults/rc.conf:

Add an example for RTADV configuration.

Set ipv6_network_interfaces to AUTO.

Switch ipv6_prefer to YES. If ipv6_enable is not set this will have
no effect.

Add a default for ipv6_privacy (NO).

9. Document all of this in rc.conf.5.

9557a45059 Add support for configuring vlan(4) interfaces as child devices similar to
wlan(4) interfaces.  vlan(4) interfaces are listed via a new 'vlans_<IF>'
variable.  If a vlan interface is a number, then that number is treated as
the vlan tag for the interface and the interface will be named '<IF>.<tag>'.
Otherwise, the vlan tag must be provided via a vlan parameter in a
'create_args_<vlan>' variable.

2e77c5abfb Fix several logic bugs in the previous IPv6 variable change and
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).

d1321a41a5 In the loop through the list of interfaces in network6_interface_setup()
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.

5090437236 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.

6da9aa1452 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.
