A historian might be able to help you. Going back to the days of
10MBps Ethernet, cards used to have a few different ports, AUI, BNC
and TP. The kernel probably supports configuring which to use,
probably via ethtool. Your use case is not that different, so you can
probably reuse it.
Extending the ethtool ops in the driver (namely mvneta) seems to be
possible and it seems that I could add more phy_dev pointers to the
private data of the driver and switch among them quite easily. But it
would be driver specific hack and I believe this problem is more
general.
Perhaps I can pass some common PHY switch command from the driver to
the prospective phy-proxy module. I'll come back to this question when
I haveproof-of-concept code.
Btw. thanks for the pointer to the phylink patchset.
