Hi, I found the my 10G network card cannot negotiate to 5G link mode after system boot. However, the link speed could recover to 5000bastT/Full after executing command "ethtool -s eth0 autoneg on". My network card is "Intel Corporation Ethernet 10G 2P X550-t Adapter". The switch is NETGEAR MS510TXPP. Here is the process to reproduce the problem: ethtool -i eth0 driver: ixgbe version: 5.15.40-Unraid firmware-version: 0x80000f32, 19.5.12 expansion-rom-version: bus-info: 0000:04:00.0 supports-statistics: yes supports-test: yes supports-eeprom-access: yes supports-register-dump: yes supports-priv-flags: yes ethtool eth0 Settings for eth0: Supported ports: [ TP ] Supported link modes: 100baseT/Full 1000baseT/Full 10000baseT/Full 2500baseT/Full 5000baseT/Full Supported pause frame use: Symmetric Supports auto-negotiation: Yes Supported FEC modes: Not reported Advertised link modes: 100baseT/Full 1000baseT/Full 10000baseT/Full Advertised pause frame use: Symmetric Advertised auto-negotiation: Yes Advertised FEC modes: Not reported Speed: 1000Mb/s Duplex: Full Auto-negotiation: on Port: Twisted Pair PHYAD: 0 Transceiver: internal MDI-X: Unknown Supports Wake-on: d Wake-on: d Current message level: 0x00000007 (7) drv probe link Link detected: yes ethtool -s eth0 autoneg on ethtool eth0 Settings for eth0: Supported ports: [ TP ] Supported link modes: 100baseT/Full 1000baseT/Full 10000baseT/Full 2500baseT/Full 5000baseT/Full Supported pause frame use: Symmetric Supports auto-negotiation: Yes Supported FEC modes: Not reported Advertised link modes: 100baseT/Full 1000baseT/Full 10000baseT/Full 2500baseT/Full 5000baseT/Full Advertised pause frame use: Symmetric Advertised auto-negotiation: Yes Advertised FEC modes: Not reported Speed: 5000Mb/s Duplex: Full Auto-negotiation: on Port: Twisted Pair PHYAD: 0 Transceiver: internal MDI-X: Unknown Supports Wake-on: d Wake-on: d Current message level: 0x00000007 (7) drv probe link Link detected: yes dmesg | grep -i ixgbe [ 39.766547] ixgbe: Intel(R) 10 Gigabit PCI Express Network Driver [ 39.766645] ixgbe: Copyright (c) 1999-2016 Intel Corporation.
