1. Limitations of the release BRS 10.3.03
=========================================

To replace the bootloader, the update must be executed again after a system reboot.
For the update, perform the steps described in the file Important_update_instructions_10.3.03.txt
 
If the file system is formatted with HiOS 08.0.00 software release or newer, a 
	downgrade to release 07.4.xx is not working.

IP version 4: Packets containing short ipv4 headers or short tcp headers and
     packets that are too short for their ip headers are dropped by the switch.
