Like most Android box devices, they ship in variants with multiple RAM, eMMC, WiFi and BT configurations. RAM and eMMC are not something we need to consider to get a working boot, but we do need to get the correct connectivity spec. Broadly speaking we see boxes with Higher and Lower spec connectivity; High spec is Gigabit Ethernet and Faster dual antennna WiFi, and Lower spec is Megabit Ethernet and a single antenna. In some low-end boxes BT is ommitted. The main reason for the RFC tag is to solicit feedback on the choice of the -100 and -1000 suffixes which are used to distinguish between devices with 10/100 Mbit (Internal PHY) or 10/100/1000 Gbit (External PHY) NIC configurations; which is important to get correct else the box will have no connectivity. I'm not a big fan of the suffixes, but earlier versions where I used -int/-ext and -mbit/-gbit resulted in users having no idea what the difference was. I'd like to informally establish a convention for this naming before doing similar things with some S905X2 devices. NB: At the current time the Realtek 8822CS and MT7668 WiFi/BT chips we have seen on 'AIR' devices are not supported in the kernel so these are deliberately ommitted. The H96-Max uses a conventional Broadcom module so has more complete support. I'm also still exploring / learning about alsa userspace configuration so for now the boxes have simple HDMI audio support; wiring up the Headphone socket will be done at a later date.
