That driver either "supports" any PHY, or none at all, depending upon
your perspective.  None of the command/status MII interface is in
place to do anything.  None of those functions are called in the
driver.  The QS6612 comment is left over from the 860T FEC driver I
copied to get the framework for the FCC driver.

The Linux 8260 FCC driver works with the supplied EST hardware and the
CTX-1170 I have.  I know it doesn't work on some others, and I don't
know if they use the same Ethernet PHY or the deal of the week.

interrogate the PHY.  In any case, this driver should work fine on
any half duplex Ethernet, and you should see transmit packets in any
case.

Then the driver must not be configuring the I/O lines correctly for
some unknown reason, or you are running full duplex without the FCC
initialized to do that.
