linux网卡信息和驱动研究

1.网卡自动识别网卡的模式有关吗？

Auto-negotiation: on

2   查看当前网卡信息

[root@VSMS ~]# lspci | grep -i eth(-i不敏感大小写)

02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 06)

dmesg | tail -f

[  733.169494] r8169 0000:07:00.0: eth0: link up

[  753.930119] r8169 0000:07:00.0: eth0: link up

BUT!!! i know how to fix it!!! it‘s not provider‘s fault it‘s broken r8169 driver!!!

3RHEL/Linux下如何找出网卡驱动的内核模块名称

filename:       /lib/modules/2.6.32-431.el6.x86_64/kernel/drivers/net/igb/igb.ko

version:        5.0.5-k

license:        GPL

description:    Intel(R) Gigabit Ethernet Network Driver

author:         Intel Corporation, <[email protected]>

srcversion:     03B6D0C3EF1D1494B300070

5 如何得知网卡是集成网卡，还是独立网卡

tar xvfz 驱动.tar.gz

cd 驱动

chmod 755 setup.sh 可能是install.sh

然后./setup.sh 或者 install.sh

Intel Corporation I350 Gigabit

因为常用的 PCI 设备都是 PnP 标准
