====== Determine network driver in use ======

  ethtool -i <network card>
  
  <network card> can be eth0 etc.

Example output:
  
  driver: e1000\\
  version: 7.3.21-k4.1-NAPI\\
  firmware-version: N/A\\
  bus-info: 0000:02:00.0

The bus-info can be coupled with lspci
   lspci -s -v "2:"
Where 2: is taken from ethtool bus-info.
