Changing Mac Magic numbers at Checkpoint Cluster

Below operation should be done at the scenario where two checkpoint clusters work on the same network.
To view the values
# fw ctl get int fwha_mac_magic
# fw ctl get int fwha_mac_forward_magic
default values are 254 and 253
Lets change them to 251 and 250
# fw ctl set int fwha_mac_magic 251
# fw ctl set int fwha_mac_forward_magic 250
Also we should write these to $FWDIR/boot/modules/fwkern.conf with hex values like the example below
fwha_mac_magic=0xfb
fwha_mac_forward_magic=0xfa
