MoCA interfaces require the use of an user-space daemon (mocad) which will typically use cmd->autoneg to force the link. This is causing other network manager applications not to get proper carrier down notifications because of the following sequence of events: - link down interrupt is received, link is set to 0 by the interrupt handler - fixed_link update callback runs and updates the BMSR register accordingly - PHY library polls the PHY for link status, sees the link is down, proceeds with reporting that - mocad gets notified of the link state and call phy_ethtool_sset() with cmd->autoneg set to the link status (0) - phy_start_aneg() is called at the end of phy_ethtool_sset() and sets the PHY state to PHY_FORCING Just make sure we notify the interface carrier appropriately when we detect that the link is down in our fixed_link update callback. This is made local to the bcm_sf2 driver as the PHY library does the right thing in any case. This is similar to the GENET change introduced in |
