This would certainly be an option to extend the format. I'm not entirely sure
where or how
the full supported format should be documented. The OpenWrt wiki seem to be
where other
config files are documented, but I don't think we support documentation in our
package
format.
Note that this package only intends to generate the bare minimum from
information
contained in board.json, which is currently a list sorted by PSE output port.
Following
the example config file:
"poe" : ["lan8", "lan7", ... , "lan1"]
Board specific power constraints also belong in board.json. For a device with
four 802.3af
ports (lan1-lan4) and four 802.3at ports (lan5-lan8) this could become:
"poe" : {
"lan1" : { "type" : "802.3af" },
...
"lan5" : { "type" : "802.3at" },
...
}
This could then be translated into a per-port "poe_type" property for example.
We also
have some discussion going on this topic for the realtek-poe package [1].
