Hi Russell, I've been working with Ioana to introduce a phylink_create_raw/phylink_attach_raw set of function that work in the absence of an attached_dev. It does not remove the netdev references from the existing code, just guards the few places that needed that. Then we plugged it into DSA (via a notifier block) and now phylink is used for both the user and non-user ports. Next step is to make the dpaa2-mac driver use this new API and send the patchset for review. Hopefully that will happen tomorrow. -Vladimir > > drivers/net/phy/phy.c | 33 ++++++++++++++++++++-------- > drivers/net/phy/phylink.c | 55 > +++++++++++++++++++++++++++++++++++++++++------ > drivers/net/phy/sfp-bus.c | 14 +++++------- > include/linux/sfp.h | 12 +++++++---- > 4 files changed, 86 insertions(+), 28 deletions(-) > > -- > RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ > FTTC broadband for 0.8mile line in suburbia: sync at 12.1Mbps down 622kbps up > According to speedtest.net: 11.9Mbps down 500kbps up
