1. Broadcom GigE on-board LAN is not working since 3.2. On 3.1 everything is fine.
2. As i know, the ROS license (Software ID) is fixed to a HDD when you first install ROS.
I've tried to move my HDD to another server with Intel NICs instead of Broadcom, but it started with another SoftwareID and said that I have no license.
