使用ethtool命令可以查看指定网卡所依赖的网卡驱动信息:
#ethtool -i em3
driver: igb - 网卡em3依赖igb驱动 version: 3.0.6-k firmware-version: 1.6-7 bus-info: 0000:08:00.0 |
04、查看网卡型号
通过③我们已经知道了网卡所依赖的驱动,但是还不知具体的网卡设备型号,此时可通过如下命令查询:
# lspci -nn | grep "Eth"

由④的操作可知当前内核(2.6.32-220.el6.x86_64)千兆网络驱动igb支持网卡型号[8086:1521],因此必须要求目标内核(2.6.33-110.el6.x86_64)对该型号网卡[8086:1521]的支持。
05、查看目标内核的网卡驱动是否支持当前型号网卡
可以通过modinfo命令查看*.ko对哪种设备型号的支持,目标内核(2.6.33-110.el6.x86_64)的相关驱动可在/lib/modules/2.6.33-110.el6.x86_64的目录中找到,如下所示:
#modinfo /lib/modules/2.6.33-110.el6.x86_64/kernel/drivers/net/igb/igb.ko
