Some new monochromatic LEDs have been introduced into DT bindings,
but they do not have corresponding descriptions on the led_colors
structure. This patch adds the missing LED color strings.
Fixes: 472d7b9e8141 ("dt-bindings: leds: Expand LED_COLOR_ID definitions")

These two types of LEDs are widely used in routers and NICs. The
RSSI (Received Signal Strength Indicator) LED is used to display
the Wi-Fi signal strength, and the Internet LED can indicate
whether the device can access a specific server.

Duplicate of 'wan'.

'rx' or 'wlan'?
Wouldn't you need multiple LEDs to indicate signal strength? Maybe
'signal' or something would be more generic?

It's different from 'wan'. 'wan' usually indicates whether the WAN
port is connected to the modem (internet services may still
unavailable). But the 'internet' shows if the device can successfully
ping servers like 8.8.8.8 to detected the internet connection status.
When the router operates in AP only mode, we can even connect LAN port
to the AC/modem to connect to the internet. In this case, 'internet'
LED should still be on. On some routers, both 'internet' and 'wan'
are available and be controled separately.
Ref: OpenWrt has a lot of devices that require the 'internet' LED：
https://git.openwrt.org/?p=openwrt%2Fopenwrt.git&a=search&h=HEAD&st=grep&s=label+%3D+.*net&sr=1
Anyway, if it is still unacceptable, please let me know and I will
remove it in v3.

'rx' and 'wlan' only shows the data transfer speed and on/off status, this
one indicates the signal strength.

Yes, usually there are 3~4 LEDs to indicate the signal strength, just like
the signal icon on the mobile phone. We can use `function-enumerator` led
property to mark the different leds in the signal group. I'll rename it to
'signal' in v3.

A similar patch was sent out two days ago, earlier than yours ;)
