我在 HP ML310e Gen 8 v2 服务器（还具有板载双端口 Broadcom BCM5720）中有一个英特尔四端口千兆以太网控制器。
当我从 Ubuntu 桌面实时 USB（16.04）启动时，所有六个端口均按预期工作：连接电缆后，它们立即建立链接，端口上的 LED 立即亮起，并且交换机上相应的 LED 也亮起。
我安装了 Ubuntu Server (16.04)，但 Intel 端口根本没有链接。LED 灯从不亮，ethtool 报告每个端口的“检测到链接：否”。使用已证实良好的电缆。Broadcom 端口工作正常。我能够使用 ethtool -p 使 Intel 卡上每个端口的 LED 灯闪烁。
我在这里发现了一份表面上类似的问题的报告：https://bbs.archlinux.org/viewtopic.php?id=159454然而这个问题已经通过以下方式解决：
echo on > /sys/bus/pci/devices/0000\:09\:00.0/power/control
（对于每个正确的 PCI ID） - 在我的例子中，该键已设置为“开”。
当我启动 Live USB 桌面时，该卡工作正常，因此我相信该卡和电缆没有问题，但我无法从已安装的 Ubuntu Server 上使其工作。这是我现在尝试的第三次从头开始安装。在之前的尝试中，我还尝试从英特尔网站下载和构建 e1000e 驱动程序，但没有任何效果。
非常感谢社区提供的任何建议 - 谢谢。

显示为 DISABLED 的接口正是 /etc/network/interfaces 中未声明的接口。请将文件修改为：

source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback

顺便说一下，如果声明的接口，eno1预计要访问互联网，则需要 DNS 名称服务器。我已冒昧地在上面的拟议编辑中提出了这一点。
重启并检查：
sudo lshw -C network
Intel 端口不再被禁用了吗？如果是这样，您可以将电缆转移到其中一个端口，重新排列 /etc/network/interfaces 并继续。
