[dpdk-dev] [RFC] app/testpmd: distinguish ICMP identifier fields in packet

[lizh]

Ability to distinguish ICMP identifier fields in packets.
Dstinguish ICMP sequence number field too.
Already supports ICMP code and type fields in current version.
Existing fields in ICMP header contain the required information.
ICMP header already is supported and no code change in RTE FLOW.
Extend testpmd CLI to include the fields of ident and sequence number.
One example:
flow create 0 ingress pattern eth / ipv4 /
 icmp code is 1 ident is 5 seq is 6 /
 end actions count / queue index 0 / end
The ICMP packet with code 1, identifier 5 and
sequence number 6 will be matched.
It will implement action counter and forward to queue 0.

Overall looks good. @Ori, any objection?

@Li, is there any PMD implementation planned to use these icmp fields?

Re: [dpdk-dev] [RFC v2 1/1] app/testpmd: distinguish ICMP identifier fields in packet

[Li Zhang]

Yes, There is PMD code change to support it.
