I'm having this issue in a fresh install of Ubuntu 20.04 with an Intel NIC and the IGC driver.

Both igb and e1000 drivers are used. All servers have strange issue: after fresh Ubuntu 16.04 installation all ethernet links are in down state even if cables are plugged in. At the network switch side links are in up state! If i try to manually up the link via ip link tool, all works fine. When i try to manually assign an IP address to "dead" interface it brings up... After reboot all links are down again. Any suggestion?
