Improving the compliance of Virtual Network Adapters with the local address bit of the MAC address rule.

Browse Source 
When installing a new device driver of the Virtual Network Driver card, we changed the initial random MAC address from 00-AC-xx-xx-xx-xx to 5E-xx-xx-xx-xx-xx. This realizes the compliance with the local address bit of the MAC address rule.
