GPIO

 * Source
 * I've gathered some of GPIO functions:

Tested by telnet:

Gathered from OpenWrt:
 * wired/wireless leds are controlled via bit shift register sitting on gpio pins 14 (ctl) and 4 (clk)
 * speed leds are controlled via bit shift register sitting on pins 17 (ctl) and 18 (clk)

Some notes:
 * restore config function doesn't work properly, the router get stucked.
 * PPPoE doesn't work with preselected want port, bridge port must be selected for wan, br0
 * current firmware level is more to instable to use it for a long period of time,
 * if there will be any new releases and if the time permits I'll test them.
