Just created a script to change the interface speed withoud reboot:
==============================================
#!/bin/ksh
##########################################################################
# Version 1.0
# This script enables changing the speed of a chozen network interface without a need fro reboot
# The user gets a list of the existing ent interfaces with teir current speed and IP setting
# Once he chooses the interfaces,he can choose the desired speed
# If you choose the speed that does not match this specific interface - the scripts gives an error
# usage : chent.sh
