I mean DPDK APIs do not exclude ipv4 options or ipv6 extension headers, it is 
bug?

主题: Re: [dpdk-dev] IPV4/IPV6 TCP/UDP Pseudo Header Checksum APIs

Realized my answer is confusing, I meant to say that code is correct as pseudo 
ipv4/ipv6 headers for the purpose of checksum calculations doesn't include 
options or extension headers, see udp wiki or corresponding rfcs

Has anybody used the following two APIs calculating ipv4&ipv6 tcp/udp pseudo 
header checksum?

1.    rte_ipv4_phdr_cksum

2.    rte_ipv6_phdr_cksum
The ipv4 version does not exclude ip options and ipv6 version does not exclude 
extersion headers.
