centos7.8降级网卡驱动r8168
概述
在外地集中开发临时租赁的window机器，临时组装成centos7.8系统的开发测试机器发现机器很不稳定，时不时宕机根据日志分析是驱动版本太高
因此，降级驱动版本保持和固件版本一致

For the "PCI: Using host bridge windows from ACPI; if necessary, use "pci=nocrs" and report a bug", this is just a kernel information message, which suggests user to file a bug if the current setting doesn't work and boot option "pci=nocrs" is needed.
