IP address defaults to wlan (might be more useful to default to eth0)

[geerlingguy]

I just realized after reading through #2 and also seeing @TiVoHomeUser's fork (main...TiVoHomeUser:SKU_RM0004:main), that the default for the IPADDRESS_TYPE is currently set to WLAN0_ADDRESS:

SKU_RM0004/hardware/rpiInfo/rpiInfo.h

Line 14 in 0e0f0ce

#define IPADDRESS_TYPE WLAN0_ADDRESS

That means my Pis, which are connected via wired network, aren't able to show their IP address.

I think for the rackmount unit, most people will be plugging in wired Ethernet, so it might make sense to default that value to ETH0_ADDRESS like @TiVoHomeUser does.
