如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,再执行此命令看看是啥输出。
- Handle 0x0020, DMI type 11, 5 bytes
- OEM Strings
下面的命令也能看出网卡控制器的制造商信息。
- [root@hvrhub ~]# lspci | grep Ethernet
