I'm currently writing a driver to configure an ethernet switch chip (see =
TL-WR1043ND on -embedded).

I noticed that there doesn't seem to be a way to power down a phy right =
now through the ifconfig media command.

Would there be objections to extend the media subtype definitions to =
include an "off", "poweroff" or "down" media subtype, and add code to =
the relevant phy drivers to power down the phy for this media subtype?

The difference between media subtype "none" and this new one would be =
that there will be no link, even if there is a physical connection.  =
With media subtype "none", a 10 MBit/s half-duplex connection is =
established, potentially confusing the remote end about the availability =
of this link.  On the local side, the link is down, so no packets are =
exchanged.
