linux下如何查看网卡驱动版本信息？

Posted 2023-03-28

Linux下查看网卡驱动和版本信息
查看网卡生产厂商和信号
查看基本信息：lspci
查看详细信息：lspci -vvv # 3个小写的v
查看网卡信息：lspci | grep Ethernet
查看网卡驱动
查看网卡驱动信息：lspci -vvv # 找到网卡设备的详细信息，包括网卡驱动
# lsmod 列出加载的所有驱动，包括网卡驱动

查看网卡驱动版本
查看模块信息：modifo<module name> # 其中包含version信息
或 # ethtool-i <device name>
RHEL 6.3中的网卡驱动版本：
# modinfo igb
filename: /lib/modules/2.6.32-279.el6.x86_64/kernel/drivers/net/igb/igb.ko
version: 3.2.10-k
license: GPL
description: Intel(R) Gigabit Ethernet Network Driver
# modinfo e1000e
filename: /lib/modules/2.6.32-279.el6.x86_64/kernel/drivers/net/e1000e/e1000e.ko
version: 1.9.5-k
license: GPL
description: Intel(R) PRO/1000 Network Driver
author: Intel Corporation,<[e-mail]>
# modinfo e1000
filename: /lib/modules/2.6.32-279.el6.x86_64/kernel/drivers/net/e1000/e1000.ko
version: 8.0.35-NAPI
license: GPL
description: Intel(R) PRO/1000 Network Driver
# modinfo ixgbe
filename: /lib/modules/2.6.32-279.el6.x86_64/kernel/drivers/net/ixgbe/ixgbe.ko
version: 3.6.7-k
license: GPL
description: Intel(R) 10 Gigabit PCI Express NetworkDriver
# modinfo r8169
filename: /lib/modules/2.6.32-279.el6.x86_64/kernel/drivers/net/r8169.ko
version: 2.3LK-NAPI
license: GPL
description: RealTek RTL-8169 Gigabit Ethernet driver
查看网络接口队列数
查看网卡接口的中断信息：#cat /proc/interrupts | grep eth0
或 # ethtool-S eth0
查看网卡驱动源码的版本号
解压Intel网卡驱动源码，打开解压缩目录下的*.spec文件查看驱动的版本。
例如：解压e1000-8.0.35.tar.gz网卡驱动后，查看e1000.spec文件。
Name:e1000
Summary:Intel(R) Gigabit Ethernet Connection
Version: 8.0.35
Release:1
Source:%name-%version.tar.gz
Vendor:Intel Corporation
License:GPL
ExclusiveOS:linux
Group:System Environment/Kernel
在驱动源码src目录中查找：
#grep DRV_VERSION * # forLinux
#findstr DRV_VERSION * # for Windows
在e1000_main.c中也能找到定义驱动版本的一行：
#define DRV_VERSION"8.0.35" DRV_NAPI DRV_DEBUG DRV_HW_PERF
在e1000e中src目录下netdev.c文件:
#define DRV_VERSION"3.0.4.1" DRV_EXTRAVERSION
igb_main.c:
#define MAJ 5
#define MIN 2
#define BUILD 9.4
#define DRV_VERSION__stringify(MAJ) "." __stringify(MIN) "."\
ixgbe_main.c:
#define DRV_VERSION __stringify(3.22.3) DRIVERIOVDRV_HW_PERF FP GA \ 参考技术A 通常，linux系统启动的时候当加载网卡的时候，会产生一条日志信息写道/var/log/messages或者dmesg里面，这里面就有比较详细的网卡信息，包括版本号码等。本回答被提问者采纳

linux下查看网卡信息的命令

rhel 内核版本号信息：

[[email protected] ~]# uname -a
Linux hvrhub 2.6.18-308.el5 #1 SMP Fri Jan 27 17:17:51 EST 2012 x86_64 x86_64 x86_64 GNU/Linux

 

查看网卡的驱动。制造商等信息：

[[email protected] ~]# kudzu --probe --class=network
-
class: NETWORK
bus: PCI
detached: 0
device: eth0
driver: r8169 ---------------->这是驱动名称，以下的modinfo命令会用到该驱动名称。

例如以下命令能看出来是不是集成网卡？---有待验证。 

[[email protected] ~]# 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，再运行此命令看看是啥输出。

Handle 0x0020, DMI type 11, 5 bytes
OEM Strings

以下的命令也能看出网卡控制器的制造商信息。

[[email protected] ~]# lspci | grep Ethernet
