v2:<br>
*Resolved merge conflicts<br>
v3:<br>
*Fixed an issue with retrieving<br>
the NIC's hardware version <br>
v4:<br>
*Moved nic info gathering step before the nics get<br>
binded to their respective drivers <br>
*Condensed some areas of code in order to make them<br>
more readable<br>
*Removed redundant None checks and added some where<br>
required<br>
*Fixed LshwOutput class to better reflect the lshw<br>
command output<br>
