例如以下指令能看出來是不是內建網卡？---有待驗證。
[[email protected] ~]# dmidecode | sed -n '/net/,+5p'
Type: Ethernet
Status: Enabled
Description: Onboard Ethernet ------------------->這個意思是不是說這是內建網卡？有機會的話，弄個pci網卡上去，再運作此指令看看是啥輸出。
Handle 0x0020, DMI type 11, 5 bytes
OEM Strings
以下的指令也能看出網卡控制器的制造商資訊。
[[email protected] ~]# lspci | grep Ethernet
