我有一台安装了CentOS 6.5的服务器,配有2x 1Gbps以太网卡,
我添加了一个新接口(英特尔(R)10千兆位PCI Express网络)但问题.
是系统没有使用(ifconfig -a)或(ifcfg-ethX)文件检测以太网信息.
我添加了一个新接口(英特尔(R)10千兆位PCI Express网络)但问题.

我尝试过以下方法：
> ifconfig -a：不显示新的NIC信息或MAC.
>删除/etc/udev/rules.d/70-persistent-net.rules并重新启动.
>尝试使用真正的HwAddr创建一个新的ifcfg-eth2文件,但仍然显示：
Bringing up interface eth2: Device eth2 does not seem to be present,delaying initialization. [Failed]
> rmmod ixgbe; modprobe ixgbe
> dmesg的输出：

这些都不起作用.
但我相信如果我格式化/重新安装操作系统它将完美地工作.
我在以前的服务器上遇到同样的问题.
如何在不重新安装操作系统的情况下解决此问题？
注意：这是在另一个全新安装的CentOS 6.5服务器上运行的相同NIC模型：
dmesg输出：

这是e1000的参数没有关于允许坏校验和的参数!!!
