Can you re-phrase your Q because it is not very clear. Got any use-case/examples for us?

Why exactly do you want to disable it? If you've got a lot of traffic, checksum offloading on the NIC will save you quite some CPU cycles?

# Checksum : configures checksum task which are offloaded to asic,
# namely transport (TCP / UDP) or network (IP) protocol checksum
# offload. By default no checksum is offloaded. Legal values are -
#       0 : No checksum offload.
#       1 : TCP & IP checksum generation is offloaded for outbound packets
#       2 : TCP & IP checksum validation is offloaded for ingress packets
#       3 : Both TCP / IP checksum is offloaded in both direction.
#  For examples, configure adapters of instance#0 and instance#3 to 
#  checksum offload.

#Checksum=3,3,3,3,3,0,0,0,0,0,0,0,0,0,0,0;
