例如我们要查看博通网卡的驱动版本，如果该机器上刚好是博通的网卡，最简单的方法就是
ethtool -i eth0
但如果我们所查看的机器用的不是博通的网卡，则可以通过以下方法查看
我们知道博通网卡的驱动文件名叫bnx2.ko
我们查找下bnx2.ko的位置
updatedb
locate bnx2.ko
结果如下
/lib/modules/2.6.32-71.el6.x86_64/kernel/drivers/net/bnx2.ko
查看驱动详细情况
modinfo /lib/modules/2.6.32-71.el6.x86_64/kernel/drivers/net/bnx2.ko
以下信息中，version记录就是我们的网卡驱动版本，是2.0.8-j15
