1- RPSU 400 integration:

This firmware brings the new communication between the GigaCore 26i and the RPSU400.
This allows the users to get a better information on the status of the power supplies,
from the web interface, or through the LEDs of both the GigaCore 26i and the RPSU 400. 

2- Added option to disable tag native VLAN on ISL
 
This menu offers the user to connect third party network devices who cannot communicate with the switch through tagged management packets.
