Try humming it in the Google or Sound Hound app. They work pretty well.

It’s CentOS 7.x

You could also check the symlinks for the device in the sysfs. The word after “drivers” below for a given network interface (eth0 below) is usually the name of the driver (cpsw below):

$ ls -l /sys/class/net/eth0/device/driver   
lrwxrwxrwx 1 root root 0 Aug  9 10:41 /sys/class/net/eth0/device/driver -> ../../../../bus/platform/drivers/cpsw

Or run lsmod and see if anything jumps out.

Either way, once you find the driver name, run modinfo to get version and other information about specific drivers.
