Two more LED functions somewhat common to wireless APs that should be
considered here IMHO are

(i) a function for cellular (3g/4g/5g/...) connectivity or activity.
LED_FUNCTION_LTE might age poorly, but LED_FUNCTION_WWAN [1] could fit
in with existing network functions.
Alternatively, LED_FUNCTION_MODEM seems both more inclusive and more specific.

(ii) a function for signaling mesh (= wireless inter-AP) connectivity
or activity.
LED_FUNCTION_MESH jumps to mind first, but perhaps there's a better
name that could fit wireless repeaters as well.
This function is close to, but does not fall IMHO under the suggested
LED_FUNCTION_SIGNAL, as this one serves to indicate activity on a
wireless connection between wireless APs (e.g. 802.11s) regardless of
signal quality.

Thanks and best,
R.

P.S.
Sorry if it looks like trying to steal the focus from OP, but I
believe it makes sense to discuss these additions here rather than
restart the discussion wrt a separate patch.
