them. Just try to run the given command on them. We need to be able to
run stop functions on interfaces that have been deleted to stop
wpa_supplicant.

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.
than one interface from the command line:
# /etc/rc.d/netif start bfe0 xl0
It's also possible to restart an interface(s):
# /etc/rc.d/netif restart bfe0
This required some changes to rc.subr(8) so that if the start/stop commands
are overidden the rest of the command line (after the start/stop/etc... cmd)
is passed through to the subroutines.
network interfaces could only be turned on and off as a group (all
static interfaces or all dhcp interfaces).
When used to start the interface a 'long form' ifconfig output is
used to show the status of the interface, but when stopping an interface
the script will simply output the name of the interface. This is simply my
personal preference. Hopefully as this functionality matures we can
stabilize on a prefered form of output for these scripts.
A stop command to the dhclient script now explicitly releases the dhcp lease.
Behaviour at system shutdown; however, is unchanged since dhclient is not,
by default, run at that time. The client will not release its lease
at shutdown.
o /etc/network.subr contains common subroutines used for seting
up network interfaces
o rc.d/hostname sets the hostname if not already set
o rc.d/nisdomain sets the nis domain *after* rpcbind but
before the yp* daemons. This fixes issues with temporary
hangs when looking up informaion in nis before it's ready.
o rc.d/netif brings network interfaces (minus dhcp) up.
o rc.d/network1 has been disabled and will be retired before
RELENG_5. It will be replaced by rc.d/netif
