Find the Network Driver Version

Use the 'ethtool' command line as follows:

#ethtool -i eth0

The output should be something similar to the following:

driver: bnx2
version: 1.7.9-1
firmware-version: 4.6.4 NCSI 1.0.3
bus-info: 0000:02:00.0

Note the buf-info value of 02:00.0. Using that value with the lspci command, we can learn more on the vendor and type of the Ethernet device

#lspci | grep 02:00.0
02:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20)

In conclusion, bnx2 is the Broadcom in-kernel Linux driver for the NetXtreme II 1G Ethernet device.
