*		MADWIFI/wlanconfig & etcnet

Starting from 0.9.6, etcnet contains another approach

for handling atheros/madwifi cards, allowing more precise

control over various operational modes, including master one,

achieved by separate iface declarations for link/ieee802.11

and one or more enslaved link/ether (also called VAPs) layers.

This approach can be selected by TYPE set to `wlan' for enslaved

link/ether iface(s), other options in this mode could be:

HOST=<link/ieee802.11 iface name, i.e wifi0>

MODE=<adhoc|ap|monitor|sta|wds> 

See also wlanconfig(8) for more detailed discussion.

Setup for bridged AP mode, ready for use with hostapd, follows:

** disallow autocreate link/ether (mandatory)

# grep ath_pci /etc/modprobe.d/options

options ath_pci autocreate=none

#

** link/ieee802.11 iface (optional)

# cat /etc/net/ifaces/wifi0/options

TYPE=eth

#

** link/ether (VAP) iface(s):

# cat /etc/net/ifaces/wlan/options

TYPE=wlan

HOST=wifi0

MODE=ap

#

** bridge iface, including wlan one:

# cat /etc/net/ifaces/br0/options 

TYPE=bri

HOST='wan lan wlan'

#

** sample hostapd configuration

# grep -v '^\(#\|ssid\|wpa_pass\|$\)' /etc/hostapd/hostapd.conf
