Two issues were found: 1. igc_get_wakeup() never sets IGC_WUFC_MAG (magic packet bit), causing igc_enable_wakeup() to always skip WOL setup and jump to pme: label without arming the NIC for magic packet wakeup. 2. The PHY Power Management register has DIS_100_D3, DIS_1000_D3, and DIS_2500_D3 bits set, which disable link speeds in D3 state and prevent the NIC from receiving magic packets after shutdown. Fix: Always set IGC_WUFC_MAG in igc_get_wakeup(), and clear the DIS_*_D3 bits in the PHPM register in igc_enable_wakeup(). -- You are receiving this mail because: You are the assignee for the bug.home | help
