So, the power budget is a global option. Do we ever envisage that parts
of this budget can be concretely assigned to specific ports or more
abstract <board sections>?
e.g.
config port
option name 'lan8'
option id '1'
option enable '1'
option budget '15'

Create a new package to generate configuration files for devices capable
of delivering power via PoE. The configuration file at /etc/config/poe
can be used by PoE daemons to configure the hardware in an implementation
specific way.
This is part of the core packages because it needs to be in sync with
the format of board.json, from which the config file is generated. The
config file structure is based on the current config file of the
realtek-poe package, but should be (and remain) implementation
independent. With a common basis, a common (LuCI) configuration
interface also becomes possible in the future.
For a device with a power budget of 130W and ports lan1-lan8 mapping to
PSE outputs 8-1, /etc/config/poe could look like (lan1-lan6 omitted):
config global
option budget '130'
config port
option name 'lan8'
option id '1'
option enable '1'
config port
option name 'lan7'
option id '2'
option enable '1'
[...]
