how to verify the current network driver name on rhel machine

Question

we have rhel 7.2 server with intel network adapters

we want to verify the Driver name by linux cli command

we not sure what is the network driver that installed ( could be i40e or e1000e or ixgbe/ixgbevf etc )

so is it possible to find the Driver name that installed on the server? by linux cli

we try by

lshw -class network

but lshw cli not installed and we want to find other way

You can parse lspci’s output to determine which drivers are currently in use (not just installed):

lspci -vmmk |
awk '/^$/ { network = 0 } /(Ethernet|Network) controller/ { network = 1 } network && /Driver:/ { print $2 }'

Once you have the driver names, modinfo will give you more information, including the driver version:

sudo modinfo i40e | grep '^version:'

is it possible to find the driver version , for example in case we want to install the driver i40e-2.12.6.tar.gz then latest version is Version: 2.12.6 – yael Oct 06 '20 at 12:14
