The integrity item allows the application to match
on the integrity of a packet.
use example:
match that packet integrity checks are ok. The checks depend on
packet layers. For example ICMP packet will not check L4 level.
flow create 0 ingress pattern integrity value mask 0x01 value spec 0x01
match that L4 packet is ok - check L2 & L3 & L4 layers:
flow create 0 ingress pattern integrity value mask 0xfe value spec 0xfe

Hi Gregory, Ori,
Can you add some samples to "testpmd_funcs.rst#flow-rules-management"?
I asked in some other thread but did not get any response, what do you think to
make 'testpmd_funcs.rst' sample update mandatory when testpmd flow added?
