networkd - how to set max WiFi transmit power level?

[Adam Nielsen <a.nielsen@xxxxxxxxxxx>]

Hi all,

I have found that in a particular WiFi set up, I get better signal
quality by lowering the transmission power on the client side (a
Raspberry Pi), with a command like this:

  iw wlan0 set txpower limit 1000

This lowers the transmit power from 31.00 dBm to 10.00 dBm.

Rather than create a systemd service to run this command at bootup, is
there a way to configure networkd to apply this setting when configuring
the network interface?

Many thanks,
Adam.
