[dpdk-dev] [PATCH v1 0/2] fix some csum errors

[Xiaoyun wang]

This patch fixes outer_l3_len parse error when
PKT_TX_OUTER_IP_CKSUM is not set, which does not affect 
checksum function, just be consistent with mbuf meta 
information description, and fixes SCTP checksum 
errors because driver doesn't pass payload offset info
to hardware, which may cause SCTP checksum error.

  - fix outer_l3_len parse error
  - fix SCTP checksum error

The actual fix is following [1] and rest is refactoring, right?
It is hard to catch the actual fix with refactoring, can you please describe the 
actual problem and fix in the commit log to clarify it?

Added following to the commit log while merging, please correct it if it is 
wrong/missing:

     The outer_l3_len is calculated wrong because 'vlan_hdr' is calculated
     wrong, 'vlan_hdr' fixed and code refactored.

Re: [dpdk-dev] [PATCH v1 1/2] net/hinic: fix outer_l3_len parse error

[Wangxiaoyun (Cloud)]

Yes,the actual fix is following as this patch:

commit 8c8b61234ffd9a283cecbf9751942cbdb87d68f6
Author: Xiaoyun Wang <cloud.wangxiaoyun@huawei.com>
Date:   Sat Jul 25 16:15:33 2020 +0800

     net/hinic: refactor checksum functions

     Encapsulate different types of packet checksum preprocessing
     into functions.

I am not asking the original patch that introduced the problem.
In this patch, the single line I put above is the only required change, right?

[dpdk-dev] [PATCH v1 2/2] net/hinic: fix SCTP checksum error

[Xiaoyun wang]

For SCTP checksum offload, pmd driver does not parse payload offset
info, which may cause hardware calculate SCTP checksum failed.
