Hi, A GE phy supports pad isolation which can save power in WOL mode. But once the isolation is enabled, the MAC can't send/receive pkts to/from the phy because the phy is "isolated". To make the PHY work normally, I need to move the enabling isolation to suspend hook, so far so good. But the isolation isn't enabled in system shutdown case, to support this, I want to add shutdown hook to net phy_driver, then also enable the isolation in the shutdown hook. Is there any elegant solution?
Or we can break the assumption: ethernet can still send/receive pkts after enabling WoL, no? Thanks in advance, Jisheng
