7.2-stable review patch. If anyone has any objections, please let me know. ------------------ From: Oleksij Rempel commit 3cdeaef1754ab8155cdd828c958ada3d36e9ad9a upstream. Force EEE off on the RTL8168h/8111h (RTL_GIGA_MAC_VER_46) at PHY connect with phy_disable_eee(). Commit 202fef9bbbf5 ("net: phy: realtek: fix EEE advertisement write on the internal PHY MMD path") made EEE actually advertise on the generic Realtek PHY; the write had been a no-op before. On the RTL8168h that un-masks a latent defect: once EEE negotiates, RX silently stalls after ~7-20 minutes. The carrier stays up, no counter or dmesg moves, and only "ip link set down/up" recovers it; disabling EEE keeps the link stable. Root-causing the RTL8168h LPI/RX path needs hardware not available now, so disable EEE for this version. Use phy_disable_eee() rather than dropping the version from rtl_supports_eee(): the latter also skips rtl_enable_tx_lpi(), whose disable branch clears the MAC TX-LPI bits (ERI 0x1b0[1:0]) on link up. rtl_hw_start_8168h_1() does not clear them (the RTL8402/RTL8106e init does), so a warm reboot from an EEE-active state could otherwise leave TX-LPI asserted while the PHY no longer negotiates EEE. Keeping the version EEE-capable preserves that clear path. This also covers the RTL8168M, which shares RTL_GIGA_MAC_VER_46.
