where to find listing of all network drivers that are installed for your kernel

You can find a listing of all the network device drivers that are installed for your kernel in the

/lib/modules/`uname -r`/kernel/drivers/net directory,

like so:
[root@serverA etc]# cd /lib/modules/`uname -r`/kernel/drivers/net
[root@serverA net]# ls


If you want to see a driver’s description without having to load the driver itself, use the modinfo command. For example, to see the description of the yellowfin.ko driver, type

[root@serverA net]# modinfo yellowfin | grep -i description

OR

you can do:- strings acenic.ko | grep description

description=AceNIC/3C985/GA620 Gigabit Ethernet driver
