我是靠谱客的博主如意美女，最近开发中收集的这篇文章主要介绍Linux启动PCI扫描出所有设备VID, DID，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

8086 VID 即代表Intel设备
10d3 DID 即代表Intel E1000_DEV_ID_82574L
150f DID 即代表Intel E1000_DEV_ID_82580_FIBER

dev_printk(KERN_DEBUG, &dev->dev, "[%04x:%04x] type %d class %#08xn",
           dev->vendor, dev->device, dev->hdr_type, class);
