Error setting up entry B2368-F20 for huawei_lte

The problem

Since around 7th July, the huawei_lte component stopped working and I no longer can retrieve information from my LTE router Huawei B2368-F20. I simply get the following error:

Sorry about the delay.

Out of interest, does that device have an Ethernet hub in it? The error occurs when we're trying to access LAN info, which provides better info on connected devices than the WiFi hosts list with units that support it. Ones that don't are expected to report error code 100002 which we do handle gracefully.

Anyway, we have a special case for error code -1 which we treat as reporting unsupported functionality too, let's make it treat 100006 similarly (the internet says 100006 could mean "parameter error", 🤷).

Likely fix in #54253
