TP-Link Filogic device discovery

For Developers
1

I've been doing some discovery of TP-Link devices based on the Filogic MT7981 and MT7986 SoC in their Omada-lineup. This was done by analyzing FCC documentation and GPL sources.

One device in this lineup is already supported by OpenWrt, the FR365. The ER7206, ER7406 and ER706W seem like exact clones of this device (the first two without WiFi). The ER707-M2, ER7212PC and ER7412-M2 share the same basic layout, but have additional switch chips and/or PHYs for 2.5Gbps + PoE.

Given the similarities, I expect that adding support shouldn't bee too difficult. Price and functionality wise, the ER707-M2 and ER7212PC seem most interesting. Does anyone have any hands-on experience tinkering with either device in the table below?

As you duly noticedit is important to record exact hardware versions. Recently tplink changes internals even with minor version changes. Also there are "alternative names" of some like ER7406V1 == G36V1
