例如以下命令能看出来是不是集成网卡？—有待验证。

[root@hvrhub ~]# dmidecode | sed -n ‘/net/,+5p’

Type: Ethernet

Status: Enabled

Description: Onboard Ethernet ——————->这个意思是不是说这是集成网卡？有机会的话，弄个pci网卡上去，再运行此命令看看是啥输出。

Handle 0x0020, DMI type 11, 5 bytes

OEM Strings

以下的命令也能看出网卡控制器的制造商信息。

[root@hvrhub ~]# lspci | grep Ethernet
