And now comes the checking of configuration specific statuses and restarting them if enabled
and necessary
NOW
Set number configuration types:
eth0 is always dhcp
if interface is not specified, it is assumed that the specified configuration applies to wlan0
ap : access point on wlan0.
Currently, address is hard-coded as 192.168.0.1 as set in hostapd (to have dhcp all on same subnet)
station : station mode on wlan0
IP address mode set in 'addtype' field. If DHCP, set as DHCP. If static, set as address field
eth0wlan0bridge :
wlan0 set as AP mode with bridge to eth0
wlan0wlan1bridge :
wlan0 set as station mode, wlan1 as ap mode with bridge
wlan1wlan0bridge
wlan1 set as station mode, wlan0 as ap mode with bridge
IN THE FUTURE
netconfigdata will have a row for each interface that needs to be configured.
Each interface can be either static, dhcp, or ap.
Each interface can also bridge, but this will be limited at first, due to the number of combinations.
If bridge is selected, the mode will be checked, and the appropriate IPTables will be set based on which one is AP
