ath79 running like a charm on my Archer C7 v2 units, but wondering why my lights weren't flashing the way I expected (specific network activity).
jeff@office:/etc$ ls -1 /sys/class/leds/ ath10k-phy0 ath9k-phy1 tp-link:green:qss tp-link:green:system tp-link:green:usb1 tp-link:green:usb2 tp-link:green:wlan2g tp-link:green:wlan5g
sed -i -e 's/tp-link:blue/tp-link:green/' /etc/config/system
As @slh points out below, the "tp-link:blue" reference in ar71xx was from older units. It's not that ath79 magically changed the colors of the LEDs, but changed the device and UCI labels to agree with many of the Archer C7 v2 production units.
