Hi Andrew, No E610 here, found it by reading the code - the X550 path (ixgbe_get_eee_fw) uses a separate FW_PHY_ACT_UD_2 activity and ixgbe_lp_map[] for partner data, the E610 path just feeds pcaps.eee_cap from REPORT_ACTIVE_CFG into lp_advertised. None of the IXGBE_ACI_REPORT_* modes return partner info so that field can't be right.
The set path goes hw->mac.ops.setup_eee() -> ixgbe_aci_set_phy_cfg(), so negotiation is in the firmware. eee_active / eee_enabled come from link.eee_status from the same FW, if those bits are right then negotiation works. Can't say more without hardware, Jedrzej or Aleksandr would know. Cheers
